FIELD: radiolocation. SUBSTANCE: after the envelope of signal is selected, correlation function has to be evaluated and its envelope has to be define. Error components of the envelope are rejected, and signals of rejected envelope are accumulated. Zero reading of envelope of correlation function is used as threshold, when that reading has been scaled according to preset level of false alarm. Device has two quick Fourier transform units 1, 7, squarers 2, 3, 8, 9, adders 4, 10, multipliers 5, 11, memory units 6, 12, accumulator 13, threshold unit 14. EFFECT: improved capability of detection of low-speed targets. 2 cl, 4 dwg
