A system to generate data channels to enhance the classification of objects by means of selective radar frequency and antenna distribution plans using signal generating and processing methods which can be utilized in conventional multifrequency radar systems. The implementation of specific synthetic ΔK algorithms for the generation of large numbers of data channels derived from the initially selected radar frequency or antenna distribution plans increases the amount of information available for classification after detection. The distance to a reflector can be uniquely resolved across virtually any range ambiguity interval, and at the same time the reflector velocity can be determined over virtually any practical velocity variation. ¿ American Geophysical Union 1996
