This paper deals with the problem of non-fluctuating target detection in the presence of a mixture of heavy tailed K-distributed clutter and independent noise. Prior papers have derived generalized likelihood ratio tests (GLRT) for this problem as well as approximations of the GLRT. These results show the required optimum processing and its vastly different efficiency as compared to similar results...
This letter deals with the problem of fluctuating target detection in heavy-tailed -distributed clutter over a number of independent coherent intervals, e.g., in the case of a long observation interval (“stare mode”), or that of independent (range) resolution cells as per the track before detect techniques. The generalized likelihood ratio test for the problem at hand is derived, as well as an...
