| 摘 要： | 基于波面的二阶谱特征,研究了粗糙海面后向散射特性并进行了数值仿真。仿真结果表明,在散射模型中考虑海浪波面的二阶谱特征时,海面微波后向散射特性呈现出随方位角和入射角等参量变化的差异,体现了粗糙海面的非线性效应。

| Abstract: | Based on the characteristics of the bispectra,this paper investigates the backscattering feature of the rough ocean surfaces,and the corresponding simulation is carried out.The simulation results indicate that when the characteristics of the bispectra are considered in the scattering model, the characteristics of the microwave scattering from ocean surfaces show the discrepancy is due to the changes of the azimuth angle and the incident angle and other parameters,which reflects the nonlinear effect of the rough ocean surfaces. |
