This report describes the second year of research for the naval Weapons Center NWC in which radar target classification techniques utilizing the resonance region are under the resonance region are under investigation. In this report, three specific topics are covered. First, the behavior of the resonance region data base classification algorithms with respect to the polarization state of the radar are studied in detail, including statistical studies of the relative disadvantages of a number of particular polarization states. Also in this part, the polarization of the signal returned from the target is processed by transformation to time domain so that a polarization transcient signature is derived. This signature forms the basis of a syntactical target classification concept. Secondly, the complex natural resonance behavior of the signal scattered from the target is studied as a function of polarization. Finally, the features utilized in the classification algorithm are studied to produce an optimization of the feature set from the point of view of the interrogating radar.
