Description

FIG. 2, a-mode accompanying; and FIG. 2,6-review mode).

A device for receiving series of pulses contains a register 1, a master oscillator 2, a time selector 3 of a pulse following period, a time selector 4 of a series following period, a counter 5, a control unit 6, a key element 7.

The control unit serves to provide two modes of operation: tracking mode and viewing mode.

A device for obtaining a series of pulses operates as follows.

From the digital computer to register 1 comes a code containing Gsl, tsser, TBP (or Weaver), mode, start time of generation of a pulse sequence (start time of the radar / np and start time) - Master oscillator 2 produces pulses with a certain frequency, arriving at the time selectors 3 (GSL) and 4 (GVR), in which the selection of pulses takes place according to Gl, Tvr codes specified from the DVM. Pulses selected in this way with the pulse frequency Gol arrive at the key element 7, which begins to pass these pulses from the time determined by the bp value specified from the digital computer or some selected sampling time interval of the simulated time diagram, and prevents the transmission of pulses with the arrival of the CVM code from the PC. Depending on the type of operating mode decrypted in control unit 6, the corresponding control signal is sent to key element 7. It is necessary to simulate the time diagram of the operation of the radar in the tracking mode at the output of the key element 7 by the control signal from the control unit 6 to allow all pulses coming from the selector 3 (G) to pass through during the time from / n-p. to the kr .. In the case of simulating the time diagram of the radar operation in the circular survey mode ceKTOpiiToro, the control signals from the control unit 6 together with the signals from the selector 4 (Tsp, Gkach) and counter 5 (tser) form a time diagram, appropriate circular view. In this case, the key element 7 permits the transmission of pulses.

from the selector 3 (Gsl), in the time intervals of the Tser series, the beginnings of which are determined by pulses from the selector 4 (Gpc, Hcp), and the number of batches is determined by the operating time interval tn.-p . and the end of the operation of the RR. Counter 5 (tser) is triggered by pulses issued by the selector 4 (GW), and counts the value specified from the DVR code

Tser is the number of pulses allocated by the selector 3 (GlS), which determine the time interval of Tser. When the set interval Tcr expires, the counter 5 outputs a control signal to the key element 7 and is reset.
