Based on temporal and spatial characterizations of IR background clutter, an optimal algorithm, which in essence, is equivalent to a maximum likelihood test, is derived for clutter suppression and target detection. The algorithm is adaptive in that the algorithm parameters (temporal and spatial correlations of the background clutter) could be continually updated if desired. The algorithm also makes use of the a priori knowledge of target intensity, whenever possible. Preliminary simulation results indicate that background clutter can be sufficiently suppressed so that the detection of low intensity targets (signal-to-noise ratio of 1) can be achieved.
