【摘要】 该文讨论了利用海洋环境探测分析雷达的回波信号反演海流径向流速的方法。文中采用搜索ＢＲＡＧＧ频点算法，能准确地从基于现代谱处理方法的谱图中找到反射信号的ＢＲＡＧＧ频点，通过计算其Ｄｏｐｐｌｅｒ频偏可推算出海流速度。对比结果表明，用ＢＲＡＧＧ频点搜索算法反演的流速与实测数据能很好地吻合。更多还原

【Abstract】 This paper presents the ocean current speed inversion using Sea Environment Sounding & Analysis Radar. A data algorithm is developed to search the BRAGG Frequency Point observed by analysis the frequency spectrum which has been dealt with modern spectrum estimate theory. The ocean current speed can be obtained by Doppler frequency deviation. Both computer simulation and actual measurement indicate that the data algorithm of BRAGG frequency point search is reliable.更多还原
