Abstract The ocean backscatter simulation is an important work for the ocean radar remote sensing application research and the design of the radar system for the ocean surveillance. Most of the ocean backscatter simulation models are based on the composite surface model, which involves the ocean wave spectrum and relax rate model. The numerous ocean spectrum and relax rate models are quite different from each other due to the different experimental and data fix methods. The different ocean spectrum and relax rate often lead to different ocean backscatter simulation results. In this paper, some typical ocean spectrum and relax rate models are used for the backscatter simulation and the results are compared with the experimental ocean scattering data. The comparison shows that the Romeiser spectrum model is better than other ocean spectrum models under the L-Ku band and 2-20m/s wind velocity, and the simulation results using different relax rate models are almost equivalent.
