FIELD: radiolocation. SUBSTANCE: proposed method is intended for use in radars selecting signals of moving targets against background of reflections from ground surface. Technical aim of invention lies in possibility of employment of system of complex phase-keyed signals with intradiscrete frequency modulation for selection of signals of moving targets received in additive mixture with signals reflected from underlying surface with simultaneous suppression of side lobes. This is achieved by formation, radiation, reception, compression of signals in matched filters with corresponding frequency modulation to form complex phase-keyed signal which is then compressed in proper matched filter. Even signal is subtracted from odd one which have maximum range according to Hamming. Subtraction results of system of signals are stored in two groups and obtained differences are multiplied in step. EFFECT: improved efficiency of method. 13 dwg
