RADAR JAMMING DEVICE

FIELD: radio engineering. SUBSTANCE: proposed device is used for jamming pulse Doppler and pulse radars. Desired jamming is attained due to high precision of determining carrier frequency of radar sounding signal and degree of fitness between parameters of signals received and those of radar to be jammed. To this end proposed jamming device using relevant connections is provided with newly introduced pulse length responding signal selector with N inputs and N outputs included in time interval measuring unit, N frequency channels, each incorporating series-connected mixer of signal- frequency estimating subsystem, intermediate-frequency amplifier, electronic selector switch, amplifier/limiter selector switch, frequency discriminator, voltage-controlled intermediate-frequency channel adjusting unit, electronic switching unit, mixer of input-signal frequency recovery subsystem, frequency-channel band filter, high-frequency preamplifier, balance modulator, output band filter, and also modulating-signal shaping device included in pulse generator and noise generator. EFFECT: enhanced spectral density of noise energy potential. 1 cl, 1 dwg
