Bistatic SAR Raw Data Simulation for Ocean

Bistatic SAR is a potential and effective tool for ocean remote sensing, and the simulation of bistatic SAR raw data from ocean surface plays a great role in the understanding of the mechanism of bistastic SAR ocean surface imaging. In this paper, a bistaitc SAR raw data simulation model for ocean surface is presented, which includes bistatic scattering simulation and ocean echo data simulation. In our research, based on IEM scattering model, a stochastic multiscale scattering model is improved by applying the second order nonlinear modulation model, and the speckle noise and coherent time character of ocean surface are simulated in the SAR raw data simulation.
