利用星载ERS-2 SAR进行长江口海面风场反演研究

Ocean Surface Wind Field Retrieval of the Yangtze River Outlet from Spaceborne ERS-2 SAR Image

摘要:

基于SAR图像反演原理,提出一种后向散射系数反演海面风场的新方法,以相关长度确定风向,再利用随机粗糙海面理论模型反演风速.并以ERS-2 SAR为数据源,以长江口海区为研究区,获取了海面风场，反演结果和浮标测量风场对比,相符得很好,证明了该方法的可行性。

Abstract:

Based on the principle of SAR image retrieval,a new retrieval approach is presented in this paper,which can evaluate wind direction,then retrieve wind speed by randomly rough sea surface theoretical model.As a case of study,a ERS-2 SAR image of the Yangtz
