Parametrization in Scattering Models,
Abstract
We discuss parametric modeling in transient wave scattering. We review global modeling based on the body resonances of the scattering object and give two examples. We explore the nature of the incompleteness of global models and introduce the concept of the local model, based on ray-optic methods. We include an example of local modeling. We show that the local model is an order of magnitude more parsimonious and more robust in the presence of noise, compared to the global model. We conclude with a discussion indicating that the local model has a better probability of success in practical target classification because of its performance in a noisy environment. (Author)
