PULSE-DOPPLER AIRBORNE RADAR STATION OPERATING METHOD DURING DETECTING OF AERIAL TARGET, RADIO RECONNAISSANCE STATION CARRIER Russian patent published in 2017 - IPC G01S13/52 

FIELD: radars.

SUBSTANCE: invention relates to radars and can be used during aerial target detection. Method consists in generation of probing pulses high-frequency sequence, their amplification by power, emitting in aerial target direction, radio reconnaissance station (RRS) carrier, receiving, amplification, conversion of reflected signals to intermediate frequencies, their selection by range and Doppler frequency, conversion of signals into digital form with their further spectral analysis, during each reception of signal reflected from aerial target, RRS station carrier, measured detection range D_ARS value is compared with maximum detection range D_RRS value of ARS emitted signal by RRS station, is meeting condition D_ARS>D_RRS making decision on, that ARS security at its operation on radiation is provided and RRS station does not detect ARS emitted signal, besides, ARS transmitter average radiated power, exposure time of aerial target, RRS station carrier and signal coherent accumulation time in ARS receiver remain unchanged, otherwise simultaneously increasing in n times, where n is integer or fractional number, larger than one, exposure time of aerial target, RRS station carrier and signal coherent accumulation time in ARS receiver and reducing ARS transmitter average radiated power in n times until, condition D_ARS> D_RRS, which testifies on provision of ARS secure operation on radiation.

EFFECT: technical result is provision of pulse-Doppler airborne radar station (ARS) secure operation on radiation during detecting of aerial target, radio reconnaissance station (RRS) carrier.
