Complex Natural Resonances of an Object in Detection and Discrimination,
Abstract
The report extends and formalizes the concept of using the complex natural resonances of objects as a tool in radar target discrimination. The complex natural resonances which characterize an object are found to be excitation invariant; i.e., the positions of the resonances in the complex frequency plane do not shift as the object is viewed along different incident directions or with different polarizations, which permit a minimum amount of data to be used in object discrimination. Once the dominant (low frequency or long time) natural resonances have been obtained for those objects of interest, a predictor-correlator type of processing can be applied to multi-frequency radar scattering data from an unknown target. It can be established from which of the known objects the scattering most likely originated. This done on the basis of correlations among the scattering and the various sets of natural resonances; the set of natural resonances showing the highest correlation identifies the most probable target.
