FIELD: radar and radio navigation.
SUBSTANCE: invention relates to radar, namely, to on-board pulse-Doppler radars operating in the narrow-band Doppler filtering mode and intended for monitoring ground or air objects. In the Doppler spectra of the measuring channels, the most plausible disjoint groups of spectral samples that correspond to the objects are distinguished according to a certain rule. Complex measurements of each distinguished group are further used to determine spatial coordinates of these objects.
EFFECT: technical result achieved is the allocation of spectral samples within the Doppler spectra of the measuring channels under the conditions of frequency oscillation.
