海洋二号卫星主被动微波遥感探测技术研究

Active and passive microwave remote sensing technology of the HY-2A ocean satellite mission

介绍了海洋二号(HY-2A)卫星4个微波有效载荷(雷达高度计、微波散射计、扫描微波辐射计和校正微波辐射计)的功能、性能和设计指标。HY-2A卫星突破了我国微波遥感设备技术上的瓶颈,为海洋环境监测预报业务化和防灾减灾提供了必要的海洋观测手段,解决了我国自主海洋动力环境参数遥感观测有无的问题。HY-2A卫星的成功发射和业务化运行为我国海洋卫星发展规划打下了坚实的基础。

The paper summarized the capabilities, performance, and technical characteristics ot the 4 payloads onboard the HY-2A satellite including radar altimeter, microwave scatterometer, scanning microwave radiometer and microwave calibration radiometer. The HY-2A satellite is marked as a significant breakthrough for microwave remote sensing technology of China, a milestone for China＇ s own ocean dynamic environment satellite that plays a crucial role in maritime applications, and a role model for China＇ s future ocean satellite missions.
