Algorithm for Detection and Identification of Low Doppler Target
ABSTRAKT
The method of detection and identification of a low Doppler target under conditions of intensive disturbances having fluctuating character is investigated in this article. The proposed algorithm for calculating the estimations of the target spatial position and the Doppler frequency translation of a signal reflected from the target is an optimum from the standpoint of the maximum of likehood. The algorithm was based on the principle of the combined processing of signals from spaced sensors in order to obtain the optimum estimations of signal parameters. The analysis is carried out both in the spectral and in the time domains which makes it possible to extract a maximum amount of information about the object under investigation with disturbances of different character and level. The results of the algorithm modeling are presented, the characteristic features of its performance in actual practice are discussed.
