Abstract

The simulation of full polarization SAR images of sea surface has great significance for both the design and evaluation of marine SAR systems and the training of SAR image application personnel. This article mainly deals with the imaging simulation of dynamic sea surface with air-borne full polarization SAR. The sea surface was simulated as a two-scale model for authenticity of simulation and appropriate speed of operation. Then, the echo of the sea surface is modeled based on suitable two-scale scattering model. At last, the article makes imaging simulations in different sea states using SAR strip-map and squint mode according to the parameters, and the effectiveness of the simulated images is justified by statistical properties of the real SAR image.
