该文对Ku波段旋转扫描星载散射计进行了仿真研究。通过仿真模型建立、分辨面元提取与风矢量模糊解消除,分析了散射计地面与星载定标特性,给出了散射计工作特性仿真结果。通过对均匀与旋涡两种模拟输入风场的仿真,表明这种旋转扫描散射计风场检测及利用Moore方程进行风场反演的有效性。

This paper invesgigates the ocean surface wind field detection of a Ku band space-borne scan-scatterometer. The resolution cell extraction method and the wind vector ambiguous solution are presented. The ground and space flight calibrating and scatterometer working characteristics are analyzed. The simulation has shown the effectiveness of wind field detection of this scatterometer and the backscatter model (Moore equation) under homogeneous and whirl wind fields respectively.
