Abstract

The primary differences in airborne radar clutter spectrum between non-sidelooking and sidelooking arrays are that its Doppler frequency of the clutter spectrum varies with the range and its clutter degrees of freedom (DOFs) are increased. In this paper, a new clutter suppression approach for non-sidelooking airborne radar based on covariance matrix taper (CMT) is proposed. Then a range ambiguous clutter suppression preprocessing method based on orthogonal projection technique is presented for non-sidelooking airborne radar with high pulse repetition frequency (HPRF). Finally the experimental simulation results indicate their correctness
