METHOD OF SURVEILLANCE PULSE DOPPLER RADAR OF TARGETS ON BACKGROUND OF REFLECTIONS FROM EARTH SURFACE

摘要

FIELD: radio engineering.;SUBSTANCE: higher speed of space surveillance is provided by low-index interval and wide-impulse hyperbolic wobble of probing parcels and realisation adapted to specifics of a composite probing signal. For each particular distance-speed element of a search space resolution the anti-noise matching is carried out between a realised configuration of an ambiguity function of a rejected received echosignal and distance-speed distribution of noise remirror capacity distribution, the received echosignal with the help of bandpass frequency filters is divided into linear FM partials, which are exposed to a separate correlation-filter processing, afterwards for every distance-speed element of search space resolution, noiseless linear frequency modulated components of target echosignals are selected and summed by vectors.;EFFECT: higher speed of space radar surveillance under exposure to remirrors from each surface due to elimination of blind distance areas that may not be viewed in a single probing cycle and realisation of an unambiguous distance-speed location of detected targets.;5 cl, 7 dwg
