The topic of the research program covers methods for target discrimination by radar scattering, making use of the natural resonances of the targets. The general plan of the program consists in a study of resonances of targets of simple shape e.g., sphere but complex composition e.g., dielectric coating of conductors during the first year, followed by simple conducting targets and comparison with parallel measurements performed at NSWC Dahlgren in the second year, with further extension to conductors of more complex shapes, using Watermans methods, later on. The emphasis of our study is two-fold, namely 1 to study ways how the resonance structure of the radar echo can be used for identifying the nature of the target the inverse scattering problem and 2 to obtain a physical understanding of the phenomena that cause the resonances, and how they manifest themselves in both steady-state and pulsed echoes. Such an understanding, in preference to a more mechanical use of the singularity expansion method, will provide us with the true capability of mastering the target discrimination problem.
