FIELD: the correlation-filter arrangement for selection of moving targets refers to radio receiving technique of processing of impulse-Doppler signals and may be used in radar systems with packet sounding signal with a great number of frequencies of repeating impulses, replaced from packet to packet.
SUBSTANCE: the arrangement has a synchronizer(11),a tracking frequency synthesizer(12), a changing heterodyne(13), a heterodyne of weight function(14), a strobe amplifier(1), a tracking compensator reject filter(2), band filters(3,7),a reject filter(4), a key(5),a mixer(6), an amplifier(8), a modulator(9), and a spectrum analyzer(10). A tracking compensator reject filter has in a direct channel an algebraic adder(15) and in a compensator channel -a heterodyne changing filter which has the first analogous multiplier(16), a narrow band filter(17),the second analogous multiplier(18) switched on one after another. The unique side reject filter(2) in comparison with the prototype ensures automatic tuning of the arrangement on the side spectrum line of interference at any quantity of frequencies of repeating impulses in a radar station.
EFFECT: increases electronic anti countermeasures of a correlation-filter arrangement in conditions of availability of powerful passive interference.
