dc.description.abstractThis investigation considers a non-linear technique for extracting natural resonances from transient electromagnetic scattering responses of radar targets. These natural resonances represent the complex poles of the target's transfer function in the Laplace transform s-plane. The advantage of their use in identification is their dependence only upon the geometry and composition of the target and not upon the aspect and polarization of the incident signal. Based on recent theoretical research, a new. signal model has been developed for describing the form of the transient scattering response. This form precludes the optimal use of previous methods for natural resonance extraction based on Prony's algorithm. In this effort, a modified least-squares approach is taken which can accommodate the actual form of the transient signal. The algorithm is tested using simulated signals with various noise levels and conclusions are drawn concerning the viability of the method.en_US
