Radar targets characterization using wavelets pyramidal decomposition

A radar target is usually characterized by its radar cross section (RCS) which is a function of the number of significant scattering points. Nevertheless, these scattering points are not sufficient to determine the target´s size. The application of wavelet pyramidal decomposition to the RCS interpretation brings significant additional information that yield to an eventual determination of the target size. This algorithm is applied to a complex target composed of one cylinder and four blades. Recognition of the target is possible along with each one of its components.
