FIELD: radio detection and ranging, applicable in the receiving devices in the conditions of action of passive jamming and at a necessity of realization of a high resolving power in range with the aid of identification of air objects or increase of the range of detection, with the resolving power remaining unchanged.
SUBSTANCE: the device has parallel channels, each including a band-pass filter, square-low phase detector, 90-deg. Phase shifter, delay line, analog-to-digital converter, buffer storage, filter unit of selection of moving targets, K delay units, K switches, output channels, each having a compression filter, modulus determining unit, threshold unit.
EFFECT: enhanced antijamming capability and resolving power in range due to enhanced dynamic range and pass-band of signals processed linearly.
