FIELD: the invention refers to radiolocation technique particularly to airborne radars of flying vehicles (fighters, helicopters).
SUBSTANCE: it is designed for providing effective discrimination of detected low-altitude low-velocity air targets and moving surface targets. The technical result is achieved due to introducing additionally seven twin-input comparators, three demultiplexers, one twin-channel multiplexer, three commutators of a signal, two logical elements "OR", two logical elements "AND" and a calculator of a supporting function in the known arrangement which has a multi-channel detector of a coherent pulse signal in the summary channel of a mono-pulse airborne radar station each channel of which includes aggregate of narrow-band ("Doppler") filters and threshold arrangements in each frequency channel; a multi-channel receiver of an elevation channel of the airborne radar station with aggregate of Doppler filters for each distant strobe; a multi-channel arrangement of forming the signal of an angular error, a commutator of distance channels, a comparator, a logical element "OR" and four logical elements "AND".
EFFECT: increases effectiveness of discrimination of low-altitude low-velocity air and moving surface targets and also decreases the number of pulses repeating frequencies used in the procedure of surveying.
