Adaptive processing of signals on a background of clutter and noise

Vladimir G. Andrejev, Tien P. Nguyen


Suppression of clutter and noise is one of the most important problems of radio location signals processing. It is shown proposed algorithm of division of processing vector into sub-vectors of non-recursive noise suppression filter allows to increase average by signals Doppler velocities probability of correct detection on 6–28% in compare to known non-adaptive whitening filter. Proposed algorithm does not require the noise correlation matrix inversion in case of modification of power of clutter noise that reduces computational burden 1.8–7 times on its realization in compare to optimal adaptive algorithm.
