HY-2卫星于2011年8月16日成功发射。它携带了四个微波仪器进入空间，在全球范围内对动态海洋环境参数进行业务观测。HY-2卫星高度计提供海面高度（SSH）、有效波高（SWH）、海面风速（SSW）和极地冰盖高程，而HY-2卫星散射计提供SSW场。同时，其机载扫描微波辐射计还可获取海表温度、风速、水蒸气和液态水含量等其他海洋和大气参数。介绍了HY-2卫星有效载荷的数据处理方法。初步结果表明，风矢量、海面高度、海面高度和海面温度符合设计技术指标。
Abstract The HY-2 satellite was successfully launched on 16 August 2011. It carried four microwave instruments into space for operationally observing dynamic ocean environment parameters on a global scale. The HY-2 satellite altimeter provides sea surface height (SSH), significant wave height (SWH), sea surface wind (SSW) speed, and polar ice sheet elevation, while the HY-2 satellite scatterometer provides SSW fields. At the same time, other oceanic and atmospheric parameters such as sea surface temperature (SST) and wind speed, water vapor and liquid water content can also be obtained by its onboard scanning microwave radiometer. In this paper, we show the data processing methods of the HY-2 satellite's payloads. The preliminary results show that wind vector, SSH, SWH, and SST conform to the designed technical specifications.
