FIELD: transport engineering; self-defense facilities.
SUBSTANCE: according to invention, Doppler frequency separation unit and higher Doppler frequency selection unit of radar contains Doppler filters readjustable in transmission band which are controlled by order generated by Doppler frequency meter.
EFFECT: reduced number of band-pass filters used for separation of signal with higher Doppler frequency.
