SUBSTANCE: the device has a control panel, memory unit, preliminary recording control unit, unit for formation of carrier relative coordinates, readout and synchronizing unit, on-line memory unit, unit for formation of video signal, unit for formation of carrier polar coordinates, noise formation unit. EFFECT: enhanced reliability of simulation of interference reflections from a disturbed sea surface. 6 dwg
The invention relates to the field of radar, namely the replicas of the signals reflected from the rough sea surface, the receiver output overview of ship radar station (radar) and can be used for education and training of the operators of the radar actions when navigating a vessel in areas with intensive navigation in difficult weather and storm conditions. It is obvious that the effectiveness of simulator training of radar operators, responsible for navigation and safety of navigation of the vessel, in determining the extent will depend on the adequacy of the simulation not only goals, but also interference of the real situation in which they have to solve the problem of detecting small objects (buoys, landmarks, boats etc), measurement of their coordinates, etc. among the various types of interference at the input of shipboard search radar, most often clutter from the rough sea surface. Accordingly there is a need in the composition of the technical means of ensuring the training of operators to provide a device mimic those of reflections. It is known a device that generates a pulse streams [1,2], but this device is only intended to configure the paths of the radar and does not take into account the shape of the antenna directional diagram for the locator, therefore cannot be used for training operators. The known device simulating various interfering environment [3], but this situation is simulated on the devices that simulate the target device systems intended for training electronic warfare. Closest to the claimed most essential features for a device containing a control unit, a memory unit, the processing unit relative coordinate media block read and synchronization, the control unit prior record, random access memory and the processing unit of the video signal is implemented by using a noise generator, a digital to analogue Converter and adder, and their relationships [4]. This device provides for the formation of the signals from the coastline in the rate of operation of the radar, however, the simulation of the signals reflected from the rough sea surface, the device selected as a prototype, is impossible because of differences in the structure of the signals reflected from the coastline, and the signals reflected from the rough sea surface, and also because of the large amount of rewritable information used for modeling the coastline that will not allow the device to operate in the rate of operation of a search radar. The task of the Britania is to ensure the formation of reflections from the rough sea surface in the rate of operation of the radar with regard to manoeuvring vessel radar in the selected area of navigation, together with the signal generator purposes [5] will allow you to test devices and algorithms for processing radar data to detect packs reflected on the purpose of the pulses on the background noise and interference reflections from rough sea surface, their support, and the education and training of the operators of surveillance radars and device processing of radar data. The technical result is to increase the reliability modeling of reflections from rough sea surface is selected in the map navigation area with the generated navigation marks fence, and, if necessary, the contour of the coastline on the radar screen of the moving vessel on the radar station. The solution is achieved that the device containing the remote control, a memory unit, the processing unit relative coordinate media (block FOCN), the control unit prior record (unit PGU), random access memory (RAM) and a shaping unit video block FVS), and the output control unit connected to the data bus to the first input of block read and synchronization unit ABC and the memory unit, the output of which is connected to data bus with the input of block FACN, the output of which is connected to data bus with the second input block is read and synchronization the third output of which is connected with the second input unit PGU, the first input of which is connected to the output of the block ABC, and the output connected to the data bus to the first input of the RAM, the second input is connected to the address bus and the synchronization to the second input block is read and synchronization, and the output connected to the data bus with the input of block FVS whose output is the second output, the first output of which is the first exit block read and synchronization entered the block of formation of polar coordinates media (block fpcn) and block the formation of noise (block FSH), and the output control unit connected to the data bus with the first input block is read and synchronization with the input of block fpcn, the output of which is connected to data bus with the input of the memory block, the output of which is connected to data bus with the input of block FACN, the first output of which is connected to data bus with the second input block is read and synchronization, and a second output connected to the data bus to the first input unit PGU, the second input is connected to the first output of the block read and synchronization, and the output connected to the first input of the block RAM, the second input is connected to the address bus and synchronization, and a second output connected to the data bus with a second input unit FVS whose output is per the first output device, a second output which is the fourth exit block read and synchronization, the third output of which is connected to data bus with a second input unit of FS, the first input of which is connected to the first output of the block RAM, and the output connected to the first input unit FVS. The ability to achieve a technical result due to the fact that the display of reflections from rough sea surface is supported by a large number of points, the dimensions of each of which is equal to the resolution radar range, and their location corresponds exactly to the map navigation area. The introduction of the generator of the reflected signals from the rough sea surface unit fpcn provides the formation of polar coordinates media radar on the specific chosen area of navigation, at the output of the radar receiver in the rate of operation of the simulated radar, which is reduced to the process of finding the necessary maps navigation area on the remote control to coordinate and move to another adjacent map navigation area in case of exceeding the boundaries of the district sailing vessel-the media radar. The introduction of the generator unit FS provides the formation of reflections from rough sea surface at the output of the radar receiver with respect to the selected konkretnogo navigation area in the rate of operation of the simulated radar. Stocktaking of the vessel to maneuver vehicle radar relative to the coastline and navigation marks fencing of the selected area is ensured by the fact that the information read from the RAM is in the direction of the current bearing of the radar antenna from the current estimated location of the carrier vessel of this radar.

The whole device can be realized with the use of computers in conjunction with analog circuits based on the well-known radioactive elements. The remote 1 control, the control unit prior record, the shaping unit relative coordinate media block read and synchronization and block the formation of the video signal similar to the blocks of the prototype. Block fpcn allows to form polar coordinates media and store them in the memory block for the given navigation area. Block photoshop allows you to create additional noise signals identical to signals reflected from the rough sea surface. Remote 1 control is used to select navigation area corresponding to the entered initial coordinates of the carrier vessel radar, to enter information about the selected mode of operation, for the water of the initial values of the rate and speed, moments of the beginning and settings maneuvers vessel radar for input conditions radar (direction and wind speed, the degree of agitation of the sea and the degree of refraction). In addition, the remote control is designed to control the modes of the pre-writing and reading information. It can be implemented using a computer keyboard and a regular panels (panels) control radar, which is expected to be implemented device simulation. Unit 4 memory consists (Figure 2) of two blocks: the digital library cards (block ABC) and the memory block. Block ABC is designed to store information about navigation areas. The memory unit is for storing information input from a remote control, data about the manoeuvring characteristics of the vessel radar, tactical and technical characteristics of the carrier vessel radar and other quantities unchanged during the formation of reflections from rough sea surface. Block e-library card (block ABC) can be implemented using long-term storage devices, magnetic media such as hard or floppy disk. Each area is made in the form of files with an individual address. Information about the navigation area is recorded in a specific area of the magnetic carrier in the next serial is major: the value of the cell with coordinates (X 0,Y0), the value of the cell with coordinates (X0,Y1),..., the value of the cell with coordinates (X0,Yn), the value of the cell with coordinates (X1,Y0), the value of the cell with coordinates (X1,Y1),..., the value of the cell with coordinates (Xn,Yn), for example, in the form of a file. When preparing the generator of reflections reads the cell values from the desired area of the magnetic carrier in the same sequence in which it was captured. The memory block may also be implemented on the basis of the computer hard drive, ROM or on the registers. The set of relative coordinates of media (block FOCN) in real time calculates the current position of the carrier vessel radar. At first after switching on the reading mode and calculating the location of the carrier unit FOKN receives data from the memory block information about the initial position of the carrier, its course and speed. The control unit prior record (unit PGU) plays the role of the translator selected information from block ABC to the input of RAM. Unit PGU can be implemented on the repeaters of the type AP with the possibility of translation outputs in high-impedance state. The block RAM can be implemented on the well-known static RAM high capacity and performance, for example CRU, sh is th these RAM is that same pins in different modes perform different functions, for example in the recording mode information are input and read output. Unit 9 reading and synchronization contains the first block 9-1 synchronization, the second block 9-2 synchronization, the third block 9-4 synchronization, the fourth block 9-5 sync generator sync signals 9-3, the first RAM 9-6, the second RAM 9-7, block 9-8 calculation of the cosine and sine of the bearing of the antenna block VCSPA), block 9-9 address generation mode read (block FARCE) and block 9-10 address generation in write mode (block FARS). The first output unit 9 read timing bus synchronization combining the synchronization signal from the first generator output 9-3 signals and sync signals from the third output of the generator 9-3 signals, the second output is the address bus and the synchronization combining the address signals from the output of the block 9-9 FARCE, the address signals from the output unit 9-10 FARS and sync signals from the output of the fourth block 9-5 signals, and the third output is the fourth generator output 9-3 added. The device operates as follows. Preparation for operation of the generator of the reflected signals from the rough sea surface is selected on the remote 1 control navigation area and enable the preview mode C is recording information. The timing diagram of operation of the generator of the reflected signals from the rough sea surface in the mode of appointment presented in figure 4. When this generator 9-3 signals at the fourth output generates a pulse cycle of pre-entry information (ICPI) with a duration of tCPS(figure 4, POS. a)that includes the block 3 PGU in broadcast mode selected information output unit 6 FOKN to the second input of the RAM 5 (figure 4, POS. b). This same pulse includes block 9-10 PART, which at its output enumerates addresses X and Y RAM 5 so that during a fixed value address X has moved consistently all the addresses Y (figure 4, POS. C, d, e, f) and thus for the time CPS sequentially formed all the addresses of the RAM cells. Synchronization information is recorded in the RAM 5 controls the fourth block 9-5 synchronization command ICPI received at its second input. The time required for preliminary entries is determined by the RAM 5 and the performance of circuit elements. When the broadcast source information 1 remote control switches to reading mode, set the initial coordinates of the carrier vessel radar, its initial course and speed, the moments and the parameters of the maneuvers of the carrier vessel radar. This information is entered from the remote control 1 control unit 4 memory as before, the AK and during operation of the generator of the reflected signals from the rough sea surface in the reading mode. In the process, enter information about the selected mode of operation. In unit 4 memory, in addition to this information, the data is stored on the manoeuvring characteristics of the vessel radar. The timing diagram of operation of the generator of the reflected signals from the rough sea surface in the reading mode are presented in figure 5. Unit 6 FOKN on the basis of the received information block 4 memory performs calculation of the current relative coordinate of the carrier vessel radar during the calculation cycle (figure 5, item a), after which it outputs the pulse cycle recording in the first RAM 9-6 (IC) (figure 5, item 6), during which the first block 9-1 synchronization on the address bus and the synchronization generates a sequence of commands loop recording information in the first RAM 9-6 (figure 5, item b). At the end of the record information block 6 FOKN starts calculating the new current position of the carrier vessel radar, and the output of the first unit 9-1 synchronization pulse is formed the end of the record information into the first RAM 9-6 (ICSI) (figure 5, item g), which is input to the second block 9-2 synchronization and puts it in standby mode for team building cycle to overwrite data from the first RAM 9-6 in the second RAM 9-7. The recurrence cycle of the calculation of Tpis determined by the time of the movement of the carrier vessel radar, moving with the maximum MSE of the awn V maxon the value of the resolution radar range Δd in accordance with the expression:
Generator 9-3 signals produces a pulse beginning of a forward stroke of the sweep (INPH) (first appearance) (figure 5, Ref. d), pulse start, reverse sweep (INAH) (second exit) (figure 5, Ref. e), and codes the current bearing and elevation of MDA radar (third exit). The repetition period INP and ENOCH (Tand), their temporal placement (tpHthe time for forward travel and toxthe time-reverse), and the sequence of change codes bearing and elevation of MDA determined mode of operation of the radar set with the remote control 1 control. The second block 9-2 synchronization on the first INP (second entrance) after the arrival of the IR SI (first entry) forms within time tCZon the address bus and the synchronization command sequence cycle to overwrite data from the first RAM 9-6 in the second RAM 9-7 (figure 5, Ref. W). The duration of tCZis determined by the ratio:
The third block 9-4 synchronization on each coming at its input INK forms for time tCZon the address bus and the synchronization command sequence cycle to overwrite data from the second RAM 9-7 in the block 9-9 FARCE (figure 5, Ref. C). The duration of tCZis determined by the ratio: <>
On the data bus of the generator 9-3 signals (the third exit) gets the code of the current bearing of the antenna unit 9-8, VCSPA. The value of the cosine and sine of the bearing MDNA is fixed at the time each INK and the data bus is supplied to the third input of the block 9-9 FARCE. With the advent of the second input unit 9-9 FARCE INP at its output is then generated addresses X and Y cells of the RAM 5 in the direction of the direction finding antenna PandRadar vessel from its current location (see Fig.6). The frequency of change of address FAndThe RAM 5 is determined by the resolution of the simulated radar range Δd in accordance with the expression:
where C is the speed of propagation of electromagnetic waves in the air, and corresponds to the frequency change increments in range. The dimensions of each discrete distance equal to the resolution radar range. The read address of the RAM cells 5 is the value of their coordinates X and Y on the point value of the range selected sequentially from the interval from 1 to m, where m is the total number of samples range defined by the equation:
where Dmax- the size of the field of view of the radar range. If Dmaxgreater distance from the vessel radar to the edge of the field of RAM in healthy lifestyles the Institute of current P andRadar, Dmaxequals this distance. When choosing the next value of the distance is increasing or decreasing per unit or address only X or only Y address, or at the same time and address X and address y Number of samples n, which is the change-of-address is determined by the ratios: where Int is a function for selecting a part number
the value of Y at the n-th discrete increments by 1,
the value of Y at the n-th discrete is not changed,
the value of Y at the n-th discrete decreases by 1
the X value at the nth discrete increments by 1,
the X value at the nth discrete will not change,
the X value at the nth discrete reduced by 1. The polling order of the cells of the RAM 5 shown in figure 5. In the survey of the first cell, when the number value of n equal to 1, the address value of X will decrease by 1 relative to the current X-position of the carrier vessel radar, and the address value of Y will be equal to the value of the current Y coordinate of the carrier vessel radar. In the survey of the second cell, when the number value of n equal to 2, the address value of X will decrease by 1 relative to the current X-position of the carrier vessel radar, as is the hell is ena Y will not change. In the survey of the third cell, when the number value of n equal to 3, the address value of X will not change, but the address value of Y will decrease by 1 relative to the current Y coordinate of the carrier vessel radar, etc. The fourth block 9-5 synchronization on every coming on his first entrance INP generates at its output during the time tCCthe command sequence cycle of reading data from the RAM 3 (figure 5, Ref. and). The duration of tCCis determined by the ratio:
When reading information about the presence or absence of the coastline with a delay relative to INP, the corresponding number of selected readings range comes from the output RAM 3 through the data bus in unit of FS, which is triggered by a signal corresponding to the logical level “0”, i.e. the signal about the lack of coastline. This signal computing unit power calculates the average power of the reflections from the rough sea surface, corresponding to the selected discrete value range, which is multiplied by the random number produced by the generator of random numbers distributed according to the Rayleigh law. This operation is performed in block multiplication. Next, the resulting signal is sent on the data bus in unit 8 FVS, where it is converted into a video signal similar to the signal reflected from the EOI is osnovnoi sea surface, which is superimposed on the screen of the radar reflection from the coastline and navigation marks fence. The shore line is a limiter for the process of forming the reflection from the rough sea surface. When reading information about the presence or absence of the coastline with a delay relative to INP, the corresponding number of selected readings range comes from the output RAM 5. To calculate the average power of the signal from the rough sea surface computing unit uses the data stored in the memory block. The computing unit can be implemented on a dedicated processor or a computer. When entering the block of FS signal corresponding to a logical level “1”, it stops working, and the next run will be made after receipt of the pulse INP, which will lead him in the ready mode. This eliminates the possibility of the formation of the signals reflected from VMP outside the coastline. At the same time information about the presence or absence of the coastline with a delay relative to INP, the corresponding number of selected readings range, also fed from the output of RAM on the data bus in unit FVS, where upon receipt of the signal corresponding to the logical level “1”, a signal is generated, similar to the signal, reflected the efforts of the shoreline. When reading information about the presence or absence of the coastline with a delay relative to INP, the corresponding number of selected readings range, also fed from the output RAM 3 through the data bus in unit 7 photoshop. Thus the fourth block 9-5 synchronization generates a pulse at the input of block 7 of FS and giving the command to check whether the coastline in the selected discrete value ranges. If there is information about the absence of the coastline in the selected discrete unit 7 photoshop generates an additional signal, similar to a radar signal reflected from a rough sea surface. If the signal at the output of block 7 FSH is produced and the block 8 FVS produces at the output a signal similar to the signal radar detection of reflections from the coastline and navigation marks fence. The device provides a simulation of the navigation area size determined by the ratio of the performance of its blocks, at times tpH, toxTandTpand the RAM 5, which for modern surveillance radars, computer equipment and radioactive elements is a field of a square, the side of which can reach several hundred kilometers. Thus, when the signals from the outputs of the generator of the reflected radar signals from the rough sea surface is displacement to the inputs of a search radar and device processing of radar data is provided by simulating the functioning of a search radar when swimming near the coastline and navigation marks fence with regard to free maneuvering of the carrier vessel radar with certainty, which allows the education and training of the operators actions when navigating the vessel in adverse weather conditions along the coast in the navigation dangerous areas of shipping, such as bays, flood zones and channels.
