Abstract
In radar cross section applications, it is well known that the electromagnetic backscattering from a complex target can be approximately modeled as if it is emanating from a discrete set of points on the target called scattering centers. The scattering center model, while only an approximation, is conceptually simple and provides a sparse abstraction of the actual target for numerous radar applications. For instance, by storing the strength and position of the scattering centers, the 1D range profile and 2D inverse synthetic aperture radar (ISAR) imagery of the target can be easily reconstructed in real time, alleviating the need for the storage of large data sets. Therefore, the extraction of the scattering center model of a target from electromagnetic signature data is an important problem1.
