Abstract

In this paper, a method of environmental geometric modeling utilizing a digital elevation model is proposed to solve the problem that the environmental modeling based on spectral function cannot describe the actual terrain. At the same time, by combining the shooting and bouncing ray (SBR) method with the facet-based scattering model (FBSM), the SBR-FBSM algorithm is proposed. Finally, the simulation analysis is carried out for the actual environment, the target environment composite scene, and the complex scene respectively to verify the rationality, and effectiveness of the proposed electromagnetic scattering algorithm and its applicability in the SAR imaging field.
