FIELD: radar devices for moving target selection using the pulse sounding signal with a low pulse repetition frequency and a high relative pulse duration.
SUBSTANCE: the claimed method for synchronous detection in pseudocoherent moving target selection systems makes it possible to refuse from the use of the complicated process of phase synchronization of the controlled local oscillator by sounding radio pulses from the radio-frequency oscillator at formation of the reference signal. It is offered to use a continuous harmonic signal from an independent oscillator as a reference signal, and excite the radio-frequency oscillator by a sequence of video pulses obtained as a result of a relatively simple procedure of frequency division of the reference signal.
EFFECT: simplified device of synchronous direction in pseudocoherent moving target selection systems.
