摘要
因为星载雷达高度计风速资料有沿轨分辨率高、精度高的特点,对其进行深入研究有重要意义。在中国海洋二号动力环境卫星刚刚升空之际,对星载雷达高度计反演海面风速国内外研究进展作一个综述。首先介绍星载雷达高度计风速反演的理论依据及存在困难;然后以风速反演进展历程为主线,分别针对后向散射系数、波浪状态、降雨、白沫等物理量引入地球物理模型函数的反演方法及强风速的反演算法进行评述,简要介绍了星载雷达高度计风速调整海面风场方法;最后对星载雷达高度计反演海面风速的进一步研究提出了几点建议。
Because of satellite radar altimeter＇s high precision and high resolution along the track,it is meaningful to lucubrate.At the moment that the HY-2 dynamic environment ocean satellite will be launched in the following years,a review of the development of surface wind speed retrieval from satellite radar altimeter is advanced.First,the basic theory of retrieving sea surface wind speed from satellite radar altimeter is introduced;second,the development of the geophysical model functions（GMF） is analyzed by the order of parameters introduced into the GMF： backscatter coefficient,wave state,rain falls,foams,etc.The method of high wind speed retrieving is also mentioned.The method to adjust the sea surface wind field by the altimeter wind speed is brefly showed.At last,some suggestions are proposed.
