海洋二号卫星是我国第一颗海洋动力环境卫星，于2011年8月16日成功发射，搭载的微波散射计是我国第一颗星载海洋风场测量雷达。海洋二号卫星微波散射计采用笔形波束体制，圆锥扫描工作方式，本文给出了微波散射计系统组成、主要性能指标和在轨数据预处理方法，并给出了在轨测试结果及在台风监测中的应用。%The HY-2A satellite was first launched in August of 2011,the microwave scatterometer as one of the main loads,is primarily applied in sea surface wind observation. HY-2A satellite scatterometer used two pencil beam circle scan system,and the radar worked in Ku band. The paper illuminates the scatterometer’s system composition,main parameter,the in-orbit pretreatment and the results in observation to typhoon.
