Abstract :
In this paper, the limitations of the conventional SNR as a measure of the matched filter performance for spatially disjoint target and scene noise will be discussed. We show that for this class of problems the matched filter expressions and the optimum processors derived under overlapping input signal and scene noise assumption may not perform well in the presence of spatially disjoint input signal and scene noise
