The p inputs of the second flip-flop 27 are respectively the R-input and -5-input, and its first and second outputs are the inverse and direct outputs, respectively.

e The device works as follows.

In the process of recording, when a source of 2 pa arrives on the fourth bus, the cycling signals of the start-up pulse S are on. The first input of the first trigger 26 sets the last one into one state. The first trigger 26 opens the first key 1i, through which an echo signal passes through the second mixer i 2 from the second bus of the source 2 radar signal. At the same time, the information input of the shift register J3 via the third source bus 2 of the dolocation signals receives pulses of digital information characterizing this echo signal. After the trigger pulse, at a time interval equal to the sounding time, a second end pulse arrives at the second input of the first trigger 26 via the fifth bus of the source 2 of radar signals, which sets the first trigger 26 to the zero state. At the same time, the first trigger 26 opens the second key 19 and closes the first key 11, which prevents the echo signal from entering the second mixer 12. A pulse of the end of the distance is fed to the input of the second standby multivibrator 15, which forms an extended pulse entering the second mixer 12 and to the input permitting the readings of the shift register 13. As a result, the pulse sequence from the output of the shift register 13 is fed through the second switch 9 to the second mixer 12. The start pulse also goes to the first waiting multivibrator 14, forming an extended pulse, the duration of which is less than the duration of the extended pulse of the second waiting multivibrator 15. In the second mixer 12, the expanded pulses of the first 14 and second 15 waiting multivibrators are mixed in positive polarity, and the echo signal from the first key 11 and the sequence of pulses from the shift register 13 are negative. From the output of the second mixer 12, the sum signal is fed to the recording-reproducing amplifier 29 — the recording-reproducing unit 5, which provides for its magnetic recording. The first bus of the source 2 radio location: the signals receive the angular position of the antenna at the first input of the modulator 1, the second input of which is supplied with a speech signal. The modulator 1 modulates at different frequencies and acts on the first mixer 4. The result of mixing in the first the mixer 4 is fed to the recording-reproducing amplifier 29 of the recording-reproducing unit 5. During playback, the playback result is fed from the second output of the recording-reproducing unit 5 to the inputs of the pulse shapers 22 and 23. Pulse generator 22 impulses trigger and end-of-distance pulses with positive polarity, while pulse generator 23 impulses an echo signal and digital polarity pulses of negative polarity. The start and end of the distance pulses arrive at the first impulse filter 17, which suppresses the shorter start impulse and inserts the end of the distance impulse to the indicator C. Moreover, in the process of extracting the end of the distance, it is delayed by the time interval coming to the first pulse 4 1ltr 17 from the synchronizer 16. The shaper 22 pulses and the first pulse filter 17 act on the third mixer 25, from the output of which the result of the mixing is fed to A second pulse filter 18 separating the start pulse arriving at the indicator 10. The start pulse from the second pulse filter 18 also goes to the second input of the second trigger 27, to the first input of which the pulse of the distance ends. When the start pulse arrives, the second trigger 27 is set to one. As a result, the echo signal from the output of the third pulse former 23 pulses, following the start pulse, passes through the third key 20 to the indicator W. The next pulse from the end of the distance coming from the first pulse filter 17 to the first input of the second trigger 27, throws the last to zero state. As a result, the digital information pulses pass through the fourth key 21. The result of the reproduction from the first output of the recording-playback node 5 is fed to a filter 6, which separates the speech signal and the antenna angle signals, which are demodulated in the demodulator 7. From the first output of the demodulator 7 The speech signal is fed to the output bus 8 of the speech signal. From the second output of the demodulator 7, signals of the antenna angular position through the first driver 9 pulses are fed to the indicator 10. Use of acquisition allows to significantly increase the recording density of radar signals.
