A procedure was developed for maximizing the signal-to-clutter ratio, of transversal filters used for moving-target-detection filters, when the frequency or the doppler shift of the signal is unknown and the noise is nonwhite. First the optimization equations were developed, using the maximum- likelihood-ratio test. Then the optimization procedure, which depends on the covariance functions of the signal and the noise, was applied to the radar MTI problem to illustrate its improvement over conventional MTI. A generalized radar doppler processor was developed by dividing the doppler space into regions and optimizing a filter for each region. The results of this process are compared with those of using conventional coherent integration filters.
