The invention relates to the field of test equipment and can be used in complex scaled-down simulation of the operation of aircraft and space objects, in particular for simulation of dynamic targets (objects)moving two-dimensionally.

A device for automated ground control missile patent RU No. 2231732, IPC 7 F 41 G 7/00, 2003.11.11, including a guided missile with a homing head (DBN), automated test equipment, measuring device responses and simulator targets, which is a Bank of data (samples) real goals in real conditions of use of the rocket, which is inserted into the collimator device for subsequent recognition of the GOS and assess its health. However, this simulator purposes does not allow you to get real change location purposes, to more accurately assess the functioning of the GOS.

Known test bench for patent RU No. 2207485, IPC 7 F 41 G 3/26, 2002.11.01 containing GOS, reflective screen and simulator targets, including the emitter signals. The reflective screen is installed in front of the simulator target. The purpose simulator includes a radiating horn mounted on a floating platform. However, this technical solution does not allow dynamic is trabocco onboard control systems in automatic mode. In addition, due to the offset GOS relatively simulator aims at moving the signal on the sphere changes the length of its passing after reflection to the receiver, which leads to systematic errors, which is a difficult task, especially when working simultaneously on multiple targets.

A known system for forecasting the results of field tests of an unmanned aerial vehicle according to patent RU No. 2160927, IPC 7 G 06 G 7/72, 2000.04.20 containing complex measuring systems, including simulator radio is designed to generate a signal simulating the movement of a monitoring object in range and simulator angular motion of objects, designed to reproduce the angular displacement of the object of observation and reflected signal. Structurally, the simulator angular motion of the object is a carrier antenna emitter connected to the output of the simulator of radio signals. The carriage moves along the guide, located at a distance, where it provides a flat wavefront at the aperture radar sight. As the antenna device is used horn radiator. The specified technical solution is the closest analogue to the stated offer and selected as a prototype. However, the data simulator aims to allow movement of the target (the object of observation) two-dimensionally. Obtaining high precision setting, i.e. the determination of the target coordinates using tools, is a complex task that requires a lot of expenses because the carriage moves along the guide that are not part of a spherical surface on which the determination of the coordinates of the emitter signal easier and more accurate. In addition, the dynamic characteristics of the motion of the object of observation (goals) do not allow to realize all possibilities known forecasting results of field tests, as not implemented by the target on the spherical surface, using and rotational motion around the circumference. The range of angles in which you can change the position of the emitter signal, small.

The present invention is to increase the reliability evaluation test results by obtaining high precision setting and expansion of radioassay purpose.

The essence of the proposed invention is that the two-step dynamic simulator contains goals connected in series signal and the emitter signals, mounted on a moving carriage, while the simulator is equipped with additional carriages with emitters of signals and vertical posts, the upper founded the eat, the top node of rotation of the upper axis of rotation, the bottom base, the bottom node of rotation, sequentially enabled by the remote control rotation, electric and mechanical rotational drive connected to the top or bottom nodes of rotation, the control unit moving the carriages, the reception unit and the transmission line control commands, the first outputs of which are connected to respective control inputs of the signal, and the second outputs to the control inputs of the respective nodes of the carriage, connected in a control unit of the radiation and the sending unit line transmission of control commands, the second input is connected to the output of the control unit moving the carriages, and the inputs of the emitter signals connected to the corresponding outputs of the signal, the upper ends of the uprights are connected to each other and at their point of connection fixed vertical axis of rotation, which is the top node of rotation fixed on the upper base, the lower ends of the vertical posts fixed in the movable part of the lower node of rotation, the stationary part is fixed on the lower base, while the receiving unit transmission line control commands and the signal are located on the rotating part of the two-step dynamic and is itator purposes, while each of the carriages placed on a vertical pole.

In the particular case of the execution of vertical rack simulator goals made curved, with the curvature has a constant radius.

In the particular case of the execution of vertical rack simulator purposes connected with the outside ring stiffness.

The receiving unit of the transfer line control commands and the signal can be fixed to the movable part of the lower node of rotation.

The vertical uprights of the carriage and sub-carriage can be performed with the internal toothed linear transfer.

Figure 1 shows the design of the proposed two-stage dynamic simulator purposes, and figure 2 - schematic view of the bottom of the rotation unit. Figure 3 shows the two-stage dynamic simulator purposes, together with a dynamic stand reproduce the movement of the GOS and the GOS,

Two-stage dynamic simulator purposes includes vertical posts 1, the carriage 2, the upper base 3, the upper axis of rotation 4, the top node of rotation 5, the remote control rotation 6, the actuator 7, the mechanical rotational drive 8, the lower the rotation unit 9 consisting of a fixed part of the bottom of the rotation unit 10 and the movable part of the bottom of the rotation unit 11, the control unit of radiation 12, the signal 13, the emitters of signals 14, b is OK control the movement of the carriage 15, the nodes move carriage 16, the transmitting unit and the transmission line control commands 17, the receiving block line command transmission control 18, the bottom base 19, the ring stiffeners 20. In addition, figures 1-3 are depicted: the homing head 21, a dynamic stand playback motion homing head 22 and the base of the dynamic Billboard motion playback GOS 23.

Two-stage dynamic simulator purposes is as follows. The control unit radiation 12 generates a command that defines the appearance simulating the target, i.e. the frequency range of the signal, its power, polarization. This command is supplied to the first input of the transmitting unit and the transmission line control commands 17, to the second input of which receives the signal from the output of the control unit moves the carriage 15, which is a command that defines the law of transfer on the corresponding vertical post 1 of the respective carriage 2. The transmitting unit transmission line control commands 17 emits a signal that carries the information received at its two inputs, and the receiving block line command transmission control 18 receives this signal and deshifriral. Thus, on his first and second outputs are signals corresponding generated by the control unit radiation 12 and the control unit moves the carriage 15, respectively, the Signal from the first output of the reception unit of the transmission line control commands 18 to the input of the processing unit 13, outputs directly and are formed corresponding signals that determine the appearance simulating the target, i.e. its frequency range, power, and polarization. These signals arrive at the inputs of the respective emitters of signals 14 that radiate into space. The signals from the second output of the reception unit and the transmission line control commands 18 are received at the inputs of the respective nodes of the carriage 16, which provide a specified movement of the carriage 2 together with the emitters of signals 14 to the vertical uprights 1. Thus, there is a movement goals in elevation. Consider changing the position of the targets in azimuth. Remote control rotation 6 generates a signal that defines the law of movement of the emitter signals 14 in azimuth: the direction, the speed, if necessary, and the acceleration that acts on the actuator 7, which is converted into rotational movement, and by means of a mechanical drive rotation 8 carries out the rotation of the two-stage dynamic simulator purposes, may be used as the top node of rotation 5, and the bottom node of rotation 9. Note that the possibility of using one of the two specified nodes of rotation 5 or 9 is an alternative characteristic and fairly included in claim 1 of the claims, because in combination with other signs, the prisoners in the claims, provides the same technical result. In two-stage dynamic simulator purposes, for testing, for example, the homing head is placed according to figure 3, the dynamic stand playback motion homing head 22 with a pre-installed homing head 21. The truncated sphere two-stage dynamic simulator purposes held for the purpose of installation in these stand 22 and the homing head 21. Figure 2 schematically shows the lower node of rotation 9, which allows you to place inside the base of the dynamic Billboard motion playback GOS 23. Positioning the radiation source 14 in a spherical coordinate system can be performed, for example, using a coordinate grid, the receipt of which is not difficult because it is a division of the circle into 360°. Spherical coordinates if necessary, can be converted to Cartesian. The definition of the azimuthal characteristics and appropriate management in azimuth is also simplified when performing bottom of the rotation unit 9 according to the type widely known tracking antenna (ADU) radar station (radar), see, for example, M.I. Finkelstein "Primary radar"), Owls. radio, 1973, str-403; "Radar devices" Ed. by what Ktsia CENTURIES Grigoriy-Ryabova, M., Owls. radio, 1970, p.93-95; LSL / Statehow, ISESCO History and development of weapons and military equipment of air defense of ground troops of Russia" publishing house "BCP", 1999, an address on the Internet - http://i.pvo.guns.ru/rtv/nitel/1113.htm#5/that can work in automatic circular mode, showing the current azimuth with a circular rotation, and in software control mode, setting and moving, ultimately, the radiation source 14, for a given program (the so-called software review space The radar). Also increasing the number of uprights 1 and carriage 2 you can get the required number of targets. In addition, increase the limit angles of movement of the carriage 2 in the horizontal plane (360°)and in the vertical plane (the critical angle depends on the degree of "truncation" mentioned earlier).

Implementation of receiving and transmitting blocks transmission line commands departments 18 and 17, respectively, can be carried out by known rules of construction of the transmission lines of information, both in analogue and digital form, see, for example, respectively the Penin P.I., Filippov LI Radio communication system, Meters, Radio and Communications, 1984, p.6-10 or Penin P.I. transmission System digital data, M, Owls. Radio, 1976, p.17-24. Given that the amount of information transmitted and the speed of its p is passing extremely low, and the transmission distance is negligible, according to the applicant, can be used with minor modifications the remote control of a TV or mobile phone, which are widely known. Moreover, the latter is already widely used for a long time as a line data transfer: GPRS for mobile Internet, GSM alarm system - an address on the Internet-http://www.zummer.ru/zummer.php?p=about. Moving and positioning of the carriage 2 along the vertical posts 1 may be, for example, using a linear gear transmission, located on the vertical posts 1, the carriage 2 and the nodes move carriage 16. The top node of rotation 5 is the case of the implementation of mechanical drive rotation on the lower node of rotation 9 plain bearing mounted on the upper base 3, and in the case of the implementation of the rotational drive to the top node of rotation 5 may be performed, as indicated earlier, on the principle of ASD radar. Node move the carriage 16 is an electric motor with a reducer. The emitter 14 may be a horn radiator for radio frequency imitating the purpose or source of light radiation when working with the appropriate TOS. The signal 13 represents the simplest case is when the set is switched and controlled by often the e and the amplitude of the signal generator or a frequency synthesizer, see for example, Shapiro, D.N., Panin A.A. fundamentals of theory of frequency synthesis, M., Chapman and hall, 1981.

The proposed two-stage dynamic simulator purposes, you can extend your booth scaled-down simulation by increasing radioassay targets up to 180° in vertical planes, and up to 360° in the horizontal plane. The accuracy setting is increased to 0.25°/min
