SAR Imagery Scattering Center Extraction and Target Recognition Based on Scattering Center Model

Based on a scattering center parametric model derived from the geometric theory of diffraction, main characteristic scattering center Fisher optimal discriminator is presented in this paper for the problem of multi-class ground targets. All aspect main characteristic scattering center recognition model and target outline characteristic curve recognition model are presented in this paper. Four-class targets (Sandia Laboratories Implementation of Cylinders II, BTR70 armored transport, T72 main battle tank and BMP2 infantry tank) in MSTAR public database are adopted in our experiments and the results are presented.
