The essence of the invention is illustrated in the figure, which shows a structural diagram of a missile simulator, including the following blocks:

1 - emitter

2 - the attenuator is smooth,

3 - converter ultra-high frequency (microwave),

4 - synthesizer

5 - power supply,

6 - block amplifier intermediate frequency (UPCH),

7 - module one-time commands,

8 - device multiplex receiving channel - radio channel (MPK-RK),

9 - power source,

10 - information display module.

The missile simulator imitates the pre-flight functions of the rocket, controls the signals coming from the carrier’s radar, and checks the electrical and informational interaction of the rocket with the carrier’s equipment.

The missile simulator contains a high frequency part and a low frequency part. The high-frequency part of the missile simulator includes an emitter 1, a smooth attenuator 2, a microwave converter 3, a synthesizer 4 and a power supply 5. The low-frequency part of the missile simulator includes an intermediate-frequency amplifier unit 6, one-time command module 7, the multiplex receiving channel device — radio channel 8, power supply 9, the information display module 10.

The emitter 1 is designed to receive a microwave signal and is a receiving antenna. Structurally, the emitter is made in the form of a section of a waveguide truncated over a wide wall with a cross section of (23 × 5) mm. To transmit a microwave signal from the emitter, the latter has a waveguide-coaxial transition to which the cable is connected.

Smooth attenuator 2 is designed to establish a certain power level of the microwave signal in the waveguide path of the simulator. Structurally, the attenuator smooth 2 is a segment of a waveguide with a dielectric plate with an absorbing coating moving parallel to a narrow wall inside it. A smooth attenuator 2 has an attenuation value of not more than 20 dB.

Microwave converter 3 and synthesizer 4 form a high-frequency block (HF). A high-frequency unit, including a synthesizer 3 and a microwave converter 4, is designed to generate an intermediate frequency signal at ten input carrier frequencies and transmit it to the intermediate-frequency amplifier unit 6.

The power supply 5 is designed to generate a supply voltage of 200 V, 400 Hz for a high-frequency unit. Power supply 5 is a single-channel power source.

The block of the intermediate frequency amplifier (IFA) 6 is designed for the main amplification and filtering of the signal at the intermediate frequency, conversion to the second intermediate frequency, frequency detection and amplification of the modulation frequencies of the input signal coming from the microwave converter 3, as well as the formation of control signals for the synthesizer 4.

The module of one-time commands 7 is designed to process incoming commands and generate commands used to control the device multiplexed receiving channel-radio channel (MPK-RK) 8: commands of the radio channel (RC), commands of the health of the interface circuits (CA) and the readiness command of the active head (AGG )

The multiplex receiving channel-radio channel (MPK-RK) 8 device processes information received via the multiplex receiving channel (MPK) and the radio channel (PK), and provides control signals to indicators of the information display module 10 of the missile simulator.

The information of the radio channel is supplied to the device by the multiplex receiving channel-radio channel 8 from the output of the UPCH 6 unit via the frequency channel discriminator circuit of the radio channel (CHRK). In the device MPK-RK 8 there is a separation of the received signals through two channels, amplitude detection, the formation of pulse signals and their digital processing.

The signals of the IPC channel enter the MPK-RK 8 device in the form of bipolar pulse signals. In the device MPK-RK 8, the received serial code is converted to parallel. The signals are sent to the indicators of the information display module 10 if the address in the received code matches the address dialed using the toggle switches installed on the panel of the information display module 10 of the missile simulator.

The missile simulator is powered by both an AC network and a 27 V DC network. Power from a 27 V DC network is provided by a power source 9 designed to generate power voltages of the UPCH 6 unit, MPK-RK 8 device and one-time command module 7 . Power source 9 is a four-channel power source.

The information display module 10 comprises a panel on which controls and displays are installed. At the same time, the controls (not shown in the diagram) are presented as a line of toggle switches for dialing the IPC address. For example, LEDs can be used as indication organs, which allow checking the following parameters: monitoring the health of the radio channel (Rev. RK) and pulse interface circuits (Rev. DS), the integrated signal of readiness of the rocket head (AGG) and monitoring the passage of frequency adjustment (PE). The panel of the information display module 10 also contains indicators of the dial-up field of the IPC channel address (Ind. Can. IPC) and indicators of the RK channel data word (Ind. Can. RK), indicators of information transmitted through the RK and IPC channels.

The missile simulator is as follows.

Functionally, the missile simulator is a device for receiving, processing and indicating information signals arriving on the high-frequency channel of the Republic of Kazakhstan, and impulse signals arriving on the circuits of the IPC channel.

At the initial stage, the presence of supply voltages is monitored. After that, the frequency of the synthesizer 4 of the missile simulator is automatically tuned to the frequency of the radio channel of the controlled object, the serviceability of the radio channel and multiplex channel, as well as the serviceability of the rocket and carrier interface circuits are monitored.

The microwave signal is received by the emitter 1 of the missile simulator and through the attenuator smooth 2 enters the input of the microwave converter 3.

Microwave converter 3 also receives a control signal from synthesizer 4, under the action of which the input microwave signal is converted into an intermediate frequency signal of 42 MHz. The intermediate frequency signal is fed to the input stage of the unit UPCH 6.

The UPCH 6 unit is a resonant amplifier with a natural resonant frequency of 42 MHz and a total passband of no more than 2 MHz. When the frequency of the signal received from the microwave converter 3 coincides with the resonant frequency of the UPCH 6 unit, a “band” signal is generated, which arrives at the one-time command module 7. The one-time command module 7 generates a control signal for the frequency adjustment indication. At the same time, the emergency indicator lights up on the front panel of the information display module 10. If the frequency of the signal received from the microwave converter 3 does not coincide with the resonant frequency of the unit 6, the “band” signal is not generated. In this case, the synthesizer 4 automatically adjusts its own output signal to the input of the microwave converter 3. The signal of the synthesizer 4 converts the input microwave signal in the microwave converter 3 into an intermediate frequency signal. In this case, the module of one-time commands 7 generates a frequency adjustment signal (PE). After the frequency of the signal received from the microwave converter 3 coincides with the resonant frequency of the UPCH 6 unit, the emergency signal is removed. Thus, the presence in the proposed scheme of the radio channel allows us to solve the problem of control and automatic adjustment of the missile simulator to a given frequency.

From the output of the UPCH 6 unit, the signal of the radio channel through the frequency discriminator circuit of the radio channel (CDRK) is fed to the input filters of the MPK-RK 8 device. The signals of the MPK channel from the main object are also fed to the MPK-RK 8 device via a twisted pair in the form of bipolar pulse signals. In the device MPK-RK 8 there is a frequency separation of the received signals through two channels, amplitude detection, the formation of pulse sequences and their digital processing, as well as the conversion of the received serial code to parallel, which improves the quality control of the operability of the interface circuits between the carrier radar and the missile, and also control of the reliability of the transmitted information along the pairing chains and the correctness of testing missile simulated missiles according to information from the carrier’s radar.

If the address in the received code coincides with the address typed on the front panel of the information display module 10 of the missile simulator, control signals are issued to indicators located on the front panel of the information display module 10. The number of the monitored pulse of the RK channel signal is selected using the switch located on the front panel of the information display module 10 of the missile simulator installed in the corresponding position.

The missile simulator allows you to control parameters in both manual and automatic mode.

When working in manual mode, the shift register containing the information sequence in the form of a binary code is zeroed, and then recording is recorded by pressing the button located on the front panel of the information display module 10 of the missile simulator. In this case, the shift register is continuously recorded information coming through the IPC chains.

To ensure control of received information to the address of the missile simulator, the address code of the controlled word is manually dialed by toggle switches located on the front panel of the information display module 10 of the missile simulator. If the code coming from the address generation circuit matches the code recorded in the shift register bits 1 to 8 in the MPK-RK 8 device, the recording of incoming information stops. On the indicators of the IPC channel of the missile simulator, the recorded information is displayed in the word with the address typed by the toggle switches on the panel of the information display module 10 of the missile simulator.

In automatic mode, it is possible to monitor changes in the information coming through the IPC circuits without pressing the buttons located on the front panel of the information display module 10 of the missile simulator.

The switching modes of the MPK-RK device is carried out by a toggle switch located on the front panel of the information display module 10 of the missile simulator.

The missile simulator allows you to automatically tune to the input signal frequency, improve the quality of monitoring the health of the interface circuits between the carrier radar and the missile, as well as control the reliability of the transmitted information on the interface circuits and the correctness of testing the commands simulated by the missile according to information from the carrier radar, which is done by splitting the circuit missile simulator for the high-frequency part, including the microwave converter and synthesizer, and the low-frequency part, as well as the use of the radio channel and mule tipleksnogo transmission channel.
