MODE OF TARGETS RADAR STATION CLEARANCE ACCORDING TO DISTANCE AND A PULSE RADAR STATION WITH COMPRESSION OF PULSES AND RESTORATION OF SIGNALS

摘要

FIELD: the invention refers to the field of radiolocation. ^ SUBSTANCE: it may be used for increasing targets clearance according to distance in ground and airborne radar stations in which radiation is executed by sounding pulses with intrapulse frequency modulation or with phase modulation. The technical result is achieved due to radiation of complex sounding signals, reception of reflected signals, their processing in a matched filter where compression of pulses is executed in time, subsequent restoration of input signals in a restoration filter. This allows to expand the effective signal band and as a result to increase clearance of the radar station according to distance. At that simultaneously the level of the lateral lobes of the compressed pulse is lowered in comparison with the results of the matched filtration and accuracy of measuring the distance to a target is increased. The usage of the invention allows increase the range of the radar station with pulse compression without reducing the clearance according to distance. The invention has two objects: the mode and the arrangement. The arrangement represents a radar station with pulse compression and restoration of signals providing increase of clearance according to distance. ^ EFFECT: increase of a radar station clearance. ^ 3 cl, 4 dwg
