Abstract :
Full-polarization scattering model and scattering center extraction are studied for high-resolution full-polarization radar systems. A new model called Coherent Polarization Geometrical Theory of Diffraction (CP-GTD) model is proposed and a novel method for full-polarization scattering center extraction is developed. The superiority of the CP-GTD is verified by experiment results.
