DEVICE FOR GENERATING RADAR STATION RESPONSE NOISE Russian patent published in 2004 - IPC

FIELD: radio engineering; electronic suppression of radar stations.

SUBSTANCE: proposed device designed to generate noise having energy potential of high spectral density due to high precision of evaluating radar sounding signal carrier, degree of compliance of parameters of signals received to those of radar to be suppressed, and improved time synchronization noise and radar signals is provided with newly introduced pulse-length signal selector; two electronically controlled receiver and transmitter matrices N x M; coding and decoding units; communication channel; two generator and transmitter frequency standards; M receiver frequency channels each incorporating series-connected signal-frequency evaluating subsystem mixer, intermediate-frequency amplifier, frequency discriminator, and analog-to-digital converter; N transmitter frequency channels each incorporating series-connected synthesized frequency oscillator, signal frequency recovering subsystem mixer, band filter, high-frequency preamplifier, balance modulator, output band filter; and also modulating signal shaping unit incorporated in series-connected noise generator and pulse generator.

EFFECT: enhanced spectral density of noise energy potential.
