HY-2A卫星雷达高度计设计及其在轨工作结果

海洋二号(HY-2A)卫星是我国第一颗海洋动力环境卫星,雷达高度计是HY-2A星的主载荷之一,发射入轨后仪器工作正常,并获得了大量有效的观测数据。该仪器在20m有效波高条件下测高精度达到了4cm,在4m有效波高条件下测高精度达到了2cm,其产品精度接近Jason-2卫星高度计。本文就HY-2A卫星雷达高度计系统设计和在轨初步结果进行论述。...

Summary:海洋二号(HY-2A)卫星是我国第一颗海洋动力环境卫星,雷达高度计是HY-2A星的主载荷之一,发射入轨后仪器工作正常,并获得了大量有效的观测数据。该仪器在20m有效波高条件下测高精度达到了4cm,在4m有效波高条件下测高精度达到了2cm,其产品精度接近Jason-2卫星高度计。本文就HY-2A卫星雷达高度计系统设计和在轨初步结果进行论述。
Bibliography:HY-2A is the first satellite for oceanic dynamic environment measurement of China. As one of main payloads of HY-2A, HY-2A radar altimeter has obtained successive measurement data after the launch. The accuracy of HY-2A radar altimeter is better than 4 cm (at 20 m significant wave height) or 2 cm (at 4 m significant wave height), which is close to that of Jason-2 satellite altimeter. In this paper, the design and in flight preliminary results of HY-2A radar altimeter are introduced.
