FIELD: radiolocating equipment.
SUBSTANCE: after quadrature-phase detection of summary and difference signals, suppression of video frequencies is carried out, where target signal shifted by Doppler frequency is a priori unavailable (mirror video frequencies). Suppression is carried out by passage of quadratures of inlet video signal through appropriate phase-shifting circuits with singular amplification, phase-frequency characteristics of which in working range are shifted in respect to each other by 90 degrees, and summation of received signals.
EFFECT: provides the possibility for giant-pulse radiolocating station to track both target signal and noise source with simultaneous increase of communication potential by target signal.
