Abstract : The ADAPT Computer Programs, (a series of empirical analysis programs based on the concept that pattern recognition and regression analysis should be preceded by a reduction in the dimensionality based on the Karhunen-Loeve expansion), were applied to composite radar signatures of two classes of targets to develop and study classification laws and mechanisms for separating the two classes. The results include definition of the significance of each of the components of the data vector to each algorithm developed. Both a two step and a number of single step algorithms were developed. The phase of the Fourier transform proved unimportant to the single step classification which were dominated by the amplitude. The phase was significant for the first step of the two step algorithm. The classification mechanisms were similar for the one step classification laws derived using 10, 30 and 200 pulses. (Author)
