FIELD: radar technology.
SUBSTANCE: invention relates to the field of radar and is intended for use in pulse-Doppler radar stations (radars) operating with highly maneuverable targets moving with variable radial velocity. The claimed device contains a digital shaper of quadrature components, a matched filter, a range-time portrait shaper, an element matrix multiplier, a range-frequency portrait shaper, a module calculator and a threshold processing unit, as well as an autofocus signal shaper, an amplitude spectrum calculator, an amplitude spectrum symmetry center calculator, a reference signal matrix shaper.
EFFECT: reduction in the number of periods of radiation and reception of packets of radio pulses in pulse-Doppler radars to compensate for the frequency modulation of Doppler signals of highly maneuverable targets.
