PULSE-DOPPLER AIRBORNE RADAR STATION OPERATING METHOD DURING DETECTING OF AERIAL TARGET, RADIO RECONNAISSANCE STATION CARRIER

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 Dvalue is compared with maximum detection range Dvalue of ARS emitted signal by RRS station, is meeting condition D>Dmaking 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> D, 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.1 cl, 2 dwg Изобретение относится к области радиолокации и может быть использовано при обнаружении воздушной цели. Достигаемый технический результат - обеспечение скрытности работы импульсно-доплеровской бортовой радиолокационной станции (БРЛС) на излучение при обнаружении воздушной цели - носителя станции радиотехнической разведки (РТР). Способ заключается в формировании высокочастотной последовательности зондирующих импульсов, их усилении по мощности, излучении в направлении воздушной цели - носителя станции РТР, приеме, усилении, преобразовании отраженных сигналов на промежуточные частоты, их селекции по дальности и доплеровской частоте, преобразовании сигналов в цифровую форму с последующем их спектральным анализом, при каждом приеме отраженного от воздушной цели - носителя станции РТР сигнала измеренное значение дальности обнаружения Dсравнивают с максимальным значением дальности обнаружения Dстанц
