FIELD: radars.
SUBSTANCE: invention is intended for use in pulse-Doppler radar stations (RLS) operating with high-speed and highly manoeuvrable targets. The claimed device comprises a digital shaper of quadrature components, a matched filter, three long-range-time portrait shapers, a long-range-frequency portrait shaper, a module calculator, a threshold processing unit, a fast Fourier transform processor, a spectrum matrix shaper, two element-by-element matrix multipliers, and an inverse fast Fourier transform processor, a phase multiplier calculator, a phase factor matrix generator, an autofocus signal generator, an amplitude spectrum calculator, an amplitude spectrum symmetry centre calculator, and a reference signal matrix generator. The listed components of the claimed device are interconnected in a certain way.
EFFECT: increased speed resolution of the radar when working with high-speed and highly manoeuvrable air targets.
