FIELD: physics. ^ SUBSTANCE: mode of the linear FM transmitter emission is carried on sliding frequency f with velocity 100 kHz/with in a narrow interval of frequencies from fin to fend=fin+100 kHz, carrying out a mode of "sawtooth waveform" with a continuance of recurring LT=1s, the linear FM is attuned on the fixed frequency fr, belonging to an interval from fin to fend=fin+100 kHz with transmission band ?f=300 Hz, and the LF exit of the linear FM receiver is connected to an inlet Y of an oscillograph which scan is carried out from an exit of the second synchronometer impulses then, delay in the synchronometer corrected, considering a mismatch of time scales of the linear FM transmitter and the linear FM receiver, and calculating under the formula ?t1=(fr-fin)/f temporary allowance which are entered in the synchronometer, then again emission of linear FM impulses is carried out, and the linear FM receiver is switched in a linear FM mode with a transmission band ?f=4 kHz and, correcting a delay in the synchronometer, achieving, that the radio signal hits the transmission band of the linear FM receiver. ^ EFFECT: cutting of time of synchromisation. ^ 1 dwg
