To the control computing device of the type are known device by author's certificates N is the rigger reject the sign of the beam, blocks matching and multiple-bit parallel adders according to the number of emitters. They implement the so-called principle of the Delta-beam control AR when each cycle of the generated control signals phasers, causing the deviation of the beam of AR at a fixed angular increments in either direction, i.e., for p cycles of operation the beam is deflected by p samples.

The closest in technical execution to the present invention is a device for control of discrete-switching AR on the author's certificate N 463977 (CL G 06 F 15/20, 1972). It contains a pulse generator, a software unit (control unit), the trigger of the sign of the deviation of the beam, blocks, matching and multiple-bit parallel accumulate adders, the number of which is equal to the number of emitters.

A disadvantage of the known devices is the inability to control the AR in the automatic tracking mode of the source.

The claimed device is directed to the task of running in AR mode, automatic tracking of the signal source. The solution of this task is possible in the case when the device for control of discrete-switching AR, consisting of generators direct and inverted outputs of which are connected with the first inputs of the first and second blocks match, second input blocks of coincidence is connected to the output of the pulse generator, the outputs of blocks matches are connected with the inputs of the bits of the parallel accumulating adders right and left relative to the axis of symmetry of the halves of the antenna array, while to the right relative to the axis of symmetry half of the antenna array inputs bits parallel accumulative adders are connected so that in the first block matches in them provides a record of the parallel binary equivalent to n - emitters, through the second block matching record parallel binary codes, in addition to the n emitters (additional code corresponds to the number (2m-n), where m is the number of bits of the parallel accumulating adders), to the left relative to the axis of symmetry half of the antenna array inputs bits parallel accumulative adders are connected to the outputs of the first and second blocks overlap so that through the first block matches in them provides a record of the parallel binary codes, in addition to the n emitters, through the second block matching record parallel binary equivalent of the numbers n of emitters, and the control unit, the United States is ontroller (MK) and the connected analog-to-digital Converter (ADC), the first input is entered logic element OR is connected to the output of the pulse generator, the second input is connected to one of the ports of the microcontroller, and the output of the element OR with a counter input trigger of the sign of the deviation of the beam, the input record (zero or one) trigger the sign of the deviation of the beam is connected to one of ports single-chip microcontroller and analog information input control unit, an information input of the analog-to-digital Converter, triggering the analog-digital Converter connected to one of the ports of the microcontroller and the control input of the control unit is designed for the exchange of information between the microcontroller and an external device, such as an external computer.

In Fig. 1 shows a block diagram of the proposed device with respect to the right half of the nine cell line emitters with a three-part phasers 180, 90 and 45 degrees. The left part of the proposed device, consisting of a similar multi-digit accumulative adders, its composition is a mirror image of the right and to simplify circuits are not shown. The phase of the Central emitter line is equal to zero and moving the beam does not change the established levels of single-chip microcontroller. In Fig. 3 shows a block diagram of the algorithm of the microcontroller in the structure of the device for control of discrete-switching AR in Fig. 4 is a block diagram of algorithm for delay pulses, and Fig. 5 is a block diagram of the algorithm that provides the implementation of the comparison function.

The proposed device comprises a unit 1, control trigger 2 the sign of the deviation of the beam, the logical element 3 OR the pulse generator 4. Direct and inverted outputs of the trigger mark deflection of the beam is connected with the first inputs of the first 5 and second 6 blocks match. The output of the pulse generator is connected directly with the second inputs of the blocks match, and through the element OR with a counter input of the trigger mark deflection. The outputs of blocks matches 5 and 6 in a certain order are connected with the inputs bits 8-12 parallel accumulative adders 7, the output unit 5 matches connected with accumulating the adders 7 so that there is record them in parallel binary equivalent to n - emitters, namely, connected to the input of the first category 8 of the first adder 7, with the input of the second discharge 9 of the second adder 7 with the input of the first 8 and second 9 discharge of the third adder 7 and the AMI 7 thus, what is record them in parallel binary codes, in addition to the n emitters (additional code corresponds to the number (2m-n), where m is the number of bits of the parallel accumulating adders 7), and, specifically, connected to the inputs bits 8-12 of the first adder 7, with inputs bits 9-12 of the second adder 7, with inputs bits 8 and 10-12 of the third adder 7 and inputs bits 10-12 of the fourth adder 7. Outputs 13 high-order bits 10-12 of the adders 7 are connected to the inputs shown in the figure matching cascades that control sections of the phasers. The numbering of the adders 7 is conducted in the figure to the right from the centerline of the lattice emitters. To the left (not shown in the figure) of the device for control of discrete-switching AR the numbering is left from the centerline, but the emitters are numbers (-n) and to reject beam, for example by one increment in the positive direction to accumulate the adders 7 left side should be recorded parallel binary codes, equivalent numbers of emitters (-n), which is achieved by recording them in codes, additional numbers n emitters. Therefore, the outputs of blocks matches 5 and 6 are connected with accumulating the adders 7 left side of the device is different to the n emitters, and the block match 6 - parallel binary equivalent to n emitters.

The control unit includes an analog-to-digital Converter 14 and a single-chip microcontroller 15. Information ADC is both analog information input 16 of the control unit, and the control input 17 is designed for information exchange microcontroller from an external device, for example with the external computer.

Single-chip microcontroller (see Fig. 2) contains the block 18 (port 1 of the microcontroller), the indicator 19 with the keyboard unit 20 (port 2), the generator 21, which control and synchronization of a microcontroller, a persistent storage unit (PCB) 22, random access memory unit (USB) 23, block special registers 24, block 25, the interrupt from the timer, an arithmetic unit (AU) 26, block 27 (port 3) and the block 28 (port 4). Transfer data, addresses, commands, control is made via the bus 29. Port 3 is an exchange of information between the microcontroller and external devices (input 17 of the control unit 1). The block 28 (port 4) connected to the digital outputs of the ADC 14. Synchronization of ADC that operates from a microcontroller. Through the block 18 (port 1) to synchronize the work generator is or unit and supplied to the input record trigger, 2 sign of the deviation of the beam.

Consider the operation of the proposed device. Through the block 19 MK (keyboard and display) offline or via the input 17 from the external device is launched into a single-chip microcontroller: initialization, programming ports 1-4 (blocks 18, 20, 27 and 28) and the choice of operation modes: search or tracking. Depending on the desired direction of the initial installation of the beam AR port 1 (block 18) MK input record zero or one trigger 2 mark deflection signal and sets the trigger 2 in the state corresponding to the deviation of the beam in the positive or negative direction relative to normals, and is prepared for the transmission of impulses block matching 5 or 6, the first of which is used to move the beam in the positive direction, and the second in the negative. The control signal from the MK 15 can flow through the inlet 17 from the external control computer and the remote manual control (block 19) of the control device.

Suppose you want to deflect the beam by one increment in the positive direction. When the trigger 2 of the sign of the deviation of the beam is in this state (positive) that the signal with his left placehouse adders 7 parallel binary code, equivalent to the number n of the radiator. This code outputs the device 13 is supplied through the key cascades section discretely switching phasers and installs them in the required state. As a result, the aperture AP is generated amplitude and phase distribution for the formation of the pattern with a maximum in a given direction.

If you need to deflect the beam by one increment in the negative direction of the trigger 2 of the sign of the deviation of the beam is transmitted to the opposite state and the pulse from the generator 4 through the outdoor unit match 6 is introduced in parallel to accumulate the adders 7 parallel binary code, additional to the number n of the radiator.

When the deviation of the beam at several increments, for example, p, in the negative direction of the trigger 2 of the sign of the deviation of the beam is in the same condition as much time as you need on passage p of the pulses from the pulse generator 4, resulting in the n-th adder is entered in the direct code number that equals the position of the beam (in this case p) to the number of n emitter that provides the deviation of the beam on the p-samples. The functioning of the left (not shown) the hours the device operates in accordance with the closest analogue. The algorithm of the control unit 1 for search modes and auto-tracking is presented in the form of a flowchart in Fig. 3. Whence it is seen that after the unit is monitoring the performance of devices based control MK with ADC, then MK programming and transition in one of the modes (search, tracking) with known parameters obtained from the outside or from PSB MK. The delay is necessary to compare the code sequences for the receiving and transmitting parts, and the comparison operation is implemented by software. Control ADC 14 and the trigger of the sign of the deviation of the beam 2 is also carried out by software.

After removing the beam in a given direction with the beginning of reception of the useful signal, the device enters the control mode of the AR for the automatic tracking of the signal source. The signals at the inputs of the recording trigger the sign of the deviation of the beam 2 (port 1 MK 15) there are no management trigger 2 is carried out by counting the entrance. Let the arrival of the first pulse from generator 4 trigger 2 the sign of the deviation of the beam is set in the positive condition, opens the block matches 5 and provides the deviation of the beam by one increment in the positive direction from ravesignal n the em activation routine to determine latency DELEY, the block diagram of the algorithm which is shown in Fig. 4. From the block diagram of algorithm of the subroutine delays imply that the parameters necessary delays represent data recorded on a particular address in the block PSB 22 MK 15. Subroutine delay is generated pulse, delayed by the time required for installation of the beam at a desired position. The subroutine occurs in two modes: search and auto-tracking. In both modes the data on the delay comes in the subroutine comparison (COMPARY). Formed a delayed pulse starts in the ADC 14, the analog information input 16 which receives the signal from the receiver with scheme high-speed automatic gain control (BAR), carrying information about the amplitude of the received signal. On receipt of the trigger pulse generated by the subroutine DELEY, the ADC 14 converts the analog signal from input 16 digital code that is transmitted to the MK 15 and processed by routine comparison (COMPARY). Routine COMPARY, a block diagram of the algorithm which is shown in Fig. 5, compares the code of the signal received on the current clock code signal received in the previous step, istwo codes current and previous sub-program will not react.

Consider the case of equality codes. In this case, the subroutine COMPARY does not generate the control pulse trigger mark 2 deflection and the next pulse from the output of the generator 4 sets the trigger 2 of the sign of the deviation of the beam in the negative state and through the outdoor unit match 6 passes to accumulate the adders 7 and provides the deviation of the beam by one increment in the negative direction from ravesignal. The next pulse generator 4 again will return the trigger 2 of the sign of the deviation of the beam in the positive condition, and the beam will be deflected by one increment in the positive direction. Therefore, when the equality code for the login routine comparison that speaks to the exact orientation of the beam on the signal source, the control device provides a serial switching the beam on one increments in positive and negative direction relative to ravesignal direction.

Let the signal source is moved in space in the positive direction from ravesignal direction. In this case, when the beam deviation in the positive direction code corresponding to the amplitude of the received signal, I is, the through which the logical element OR 3 will be held at the counting input of the trigger 2 of the sign of the deviation of the beam and throw it in idle, negative state. But since there is no pulse output from the generator 4, any changes in the state of accumulative adders 7 does not occur, and accordingly does not change the position of the beam. The following comes from the pulse generator 4 returns trigger 2 in the work (positive) condition and moves the beam by one increment in the positive direction, and so on, That is, a beam of AR will catch up passing in the positive direction of the signal source.

When clearing codes when ravesignal direction looks at the signal source, the device will provide sequential switching of the beam on one discretes around ravesignal direction, as described above.

When moving the source signal in the negative direction operation of the device is similar to that described above, but the workers are negative state trigger 2 the sign of the deviation of the beam, and single - positive status.

Thus, during the operation of the device the input voltage source. When the signal is lost, control is passed to the operator or the external computer through the block 19 and respectively through the control input 17 of the device set the trigger 2 of the sign of the deviation of the beam in the state, providing the output beam of a given point of the expected signal, or a search for a given program similar to that implemented in the next version. When the signal device again continues to operate in the auto-tracking mode.

As a microcontroller you can use a standard single-chip microcontroller series 1816 (/Century Century Stalin, A. C. Urusov, O. F. Malagentia. The design of digital devices on a single-chip microcontrollers. M, Energoatomizdat. 1990/). The remaining components of the structural scheme of the device can be performed on the elements TTLS series 1533, 1554 as suggested in the prototype. Type select the ADC will be determined by the requirements of the temporary parameters necessary to ensure the health of the device control and the specified accuracy characteristics defined by the bit depth Converter (high-speed integrated circuits DAC and ADC and measurement of their parameters / A. Th.- M.: Radio and communication, 1988, S. 20-29, 60-100).
