NONLINEAR RADAR FOR SPOTTING EXECUTIVE RADIO-ELECTRONIC DEVICES OF CONTROLLING THE BLAST Russian patent published in 2005 - IPC

FIELD: radiolocation and may be used at developing mobile nonlinear radars for remote detection of radio-electronic devices of controlling the blast.

SUBSTANCE: nonlinear radar for detecting executive radio-electronic devices of controlling the blast has reference generator, the first devisor of the frequency, linear frequency modulated generator, power amplifier, filter of lower frequencies, transmitting and receiving antennas, the first bandwidth filter, mixer, second bandwidth filter, receiver and radar scope. The invention introduces a third bandwidth filter, second devisor of frequency, fourth bandwidth filter, second mixer, fifth bandwidth filter, former of probing linear frequency modulated signal, third mixer, sixth bandwidth filter, band-elimination filter, fourth mixer, block of filters of exact selection, seventh bandwidth filter, former of a heterodyne linear frequency modulated signal and block of heterodyne signals. The introduction of new blocks into nonlinear radar decreases the influence of the harmonics of the probing signal incoming into the receiving device from transmitting antenna and reflected from underlying terrain. This increases the distance of detecting the objects with nonlinear diffuser more than three times as much and at the same time increases frequency selectivity of the receiver.

EFFECT: increases the distance of detecting of executive radio-electronic devices of controlling the blast at the expense of decreasing the influence of harmonics from transmitting antenna and reflected from underlying terrain.
