FIELD: radiolocation.
SUBSTANCE: in device, subtracting device is made on potential-scopic tubes, consisting of two quadrature channels, containing phase detectors, subtracting devices, and also common adder, combining outputs of both channels, while in each channel between subtracting device and adder balance modulators are connected, as support voltage of which voltage fed onto phase detectors of appropriate channel is used.
EFFECT: restoration of frequency-phase structure of signals.
