Abstract

In this paper the problem of detection of COHERENT radar signals with slow fluctuating amplitude and UNKNOWN DOPPLER SHIFT in NON-GAUSSIAN CLUTTER is considered. COHERENT radar signal detection with UNKNOWN DOPPLER SHIFT is rarely considered in the literature. It has been demonstrated that in high resolution radars or in small grazing angles, the pseudo-Gaussian models are more accurate than Gaussian for clutter modeling. Optimum detection of signals with UNKNOWN DOPPLER SHIFT in pseudo-Gaussian clutter contains a complicated multiple integral. Therefore, in this paper, generalized forms of the suboptimum GLR and CGLR detectors are proposed. Also, by estimating the random variable related to the clutter power (τ) in the test cell, GLRTLQ detector for UNKNOWN DOPPLER SHIFT case is introduced and generalized. It is demonstrated that the proposed GLRTLQ detector has a simple structure and does not depend on the clutter distribution. The performances of the proposed detectors are evaluated by computer simulation.
