Abstract

We present a mathematical framework for investigating the spatial covariance properties of wideband radar signatures from complex targets. The phrase 'complex target' is used to describe the target consisting of a large number of discrete scattering centers distributed over an electrically large volume (such as military air and ground targets). The spatial covariance properties of the scattered field are found to depend primarily on the volume density of the scattering centers and the scattering geometry. The results are presented within a general framework that includes bistatic scattering geometries. Characterizing signature covariance properties is important because they play a significant role in determining the performance of automatic target recognition systems as well as in the design of optimal detection and classification algorithms.
