Scattering center analysis via Prony´s method

High-frequency scattering can often be described in terms of scattering centers, and an understanding of the geometries which give rise to these centers is important in the area of radar cross section modification. Certain canonical geometries have been treated theoretically with asymptotic methods, but, in general, one must study the behavior of scattering centers empirically. Prony´s method provides a way of extracting the locations (projected on the path of propagation) and weighting coefficients of scattering centers from the backscattered field as a fuction of frequency. It has been found to be superior to the conventional Fourier transform technique in resolution and dynamic range.
