FIELD: radio engineering.
SUBSTANCE: device has in series connected intermediate frequency amplifier, matched filter, amplitude demodulator, incoherent stacker, and unit for detecting echo-signals, as well as circular scan display unit, the first angels valve and selector having the second valve, fast Fourier transformation unit, unit for selecting local maximums, Doppler accumulation filter, rejection filter set and threshold unit provided with appropriate links.
EFFECT: improved noise immunity; high probability in detecting signals from small-sized and hardly-distinguishable targets.
