FIELD: physics.
SUBSTANCE: method includes as follows. Horizontal and vertical orientation characteristic static fan receives noise signals in combination with frequency-time processing within each spatial observation channel, quadrating, time averaging, alignment and signal normalising to interference, observation of current view cycle for received normalised signals and detection decision-making comparing to limit value of signal-interference relation. Thus within each view cycle for each frequency sample the adaptive spatial observation channels are formed, at least by three adjacent spatial channels in horizontal or vertical plane.
EFFECT: improved reliability of detection and long contact with noisy moving target in the sea.
