In this paper,we study the method of wave telemetry by ship motion in navigation of S-band radar.Firstly,based on the basic principle of coordinate transformation,we transformed geography coordinate into ship coordinate and got the azimuth and elevation angle after calibration.Secondly,with the method of grid division,we find the public area of antenna illuminating and the motion compensation of shipborne radar is realized.Finally,the method was used to deal with the simulation model.The results show that this method is a promising method to measure ocean wave for shipborne S-band wave telemetry radars. 船载 走航观测 S波段海浪遥测雷达 姿态校准 shipborne navigation S-band wave telemetry radars calibration 10.14188/j.1671-8836.2014.03.012 TN959.72 国家高技术研究发展计划（863计划）项目（2006AA09A303）;国家自然科学基金资助项目（40976105,41376182）;中央高校基本科研业务费专项资金项目（274020,114003,2012212020203）;海洋公益性行业科研专项重大项目（201205032）;中国国家博士后科学基金（2013M531738）资助 2014-03-01 2021-04-01 3 60
