FIELD: radar.
SUBSTANCE: invention relates to radar and can be used in short-range radar stations of decimetre range and is intended for selection of targets moving on jamming background. Said technical result is achieved due to that in known method inter-period processing, based on preliminary coherent passive jamming rejection and accumulation of useful signal using a multichannel system of coherent inter-period filters, each of which is matched with a certain frequency of a Doppler signal, passive jamming signal approximation is carried out by its projection on a finite-dimensional subspace and weight vector is derived using a specific formula, and coherent accumulation of useful signal is carried out, after which useful signal is extracted from obtained signal by means of a given threshold on a threshold device.
EFFECT: technical result is high efficiency of noise-immunity of radar station in presence of jamming due to minimisation of losses when detecting useful signal.
