Orbit Performances Validation for CFOSAT Scatterometer

  • 摘要: 中法海洋卫星(CFOSAT)微波散射计是国际上第一个旋转扇形波束体制散射计,通过优化雷达观测几何实现对地面目标多角度和多方位的高精度测量,提高海面风场、土壤湿度和海冰面积等地球物理参数的反演精度.根据CFOSAT卫星2018年10月发射以来的在轨测试数据,结合散射计系统特点,分析验证了星上定标数据和后向散射系数反演结果的正确性,并对CFOSAT首批科学数据进行了定量分析和系统评价.结果表明,CFOSAT散射计在轨工作状态良好,实际性能与设计预期一致,风速测量精度优于1.5m·-1,风向测量精度优于15°,空间分辨率可达12.5km,在近岸风场监测、土壤湿度遥感和海冰面积估计等应用领域具有独特的优势.
