Abstract In this paper, related issues of SAR retrieving ocean surface wind in near shore are discussed thoroughly. First, a method of estimating ocean surface wind direction in near shore is proposed, which uses wind direction of closed ocean surface to estimate needed ocean surface wind direction in near shore based on minimum distance principle. Second, a retrieval method of ocean surface wind speed in near shore using ENVISAT/ASAR IM imaging mode PRI data is given, which Geophysical Model Function (GMF) models’ capability is compared and a segment retrieval algorithm of ocean surface wind speed is proposed. They constitute an integral method of SAR retrieving ocean surface wind in near shore. By experiment and comparison, the effectiveness and rationality of above mentioned method are verified.
