FIELD: radar.
SUBSTANCE: invention can be used for all-angle recognition in a pulse-Doppler radar station (radar) of the typical composition of a group air target (GAT) under various flight conditions and the influence of speed-deflecting interference. In the claimed method, Doppler frequency samples are simultaneously filtered in Kalman filters from their first group with the first dynamic model and from their second group with the second dynamic model, respectively, as a result of which a corresponding estimate is formed at the output of each Kalman filter from the first and second groups Doppler frequency with different filtering error variances. Based on the corresponding estimate at the output of the Kalman filter from the first group, a decision is made that the signal is due to reflections of the radar signal from the i-th aircraft of the group, which has the j-th type with q-th flight conditions. According to the corresponding estimate at the output of the Kalman filter from the second group, a decision is made that there is an influence of contusion interference according to the w-th law with the r-th variant of the parameters of the speed-contusion interference.
EFFECT: ensuring recognition in a pulse-Doppler radar with a given probability of the typical composition of the main computer at various angles of its radar observation flight conditions and the influence of speed-deflecting interference.
