中文摘要：

建立单矢量水听器简正波接收模型,引入高分辨算法构造代价函数对目标的距离和角度进行匹配搜索,实现对浅海中水面目标的定位。仿真结果表明：当接收信噪比不低于15 d B时,该方法依靠单矢量水听器就可以对水面目标进行定位。通过海试数据处理结果分析,在3 km范围内,在较高信噪比时,定位误差小于5%。实验数据验证了算法的有效性。

英文摘要：

Normal mode reception model of single vector hydrophone is established,and azimuth and distance of target are searched by cost function which is structured by high-resolution DOA estimation to realize sea surface target localization. Simulation results show that sea surface target in shallow water can be located when receiving SNR is higher than 15 d B,the method can locate sea surface target by single vector hydrophone. Through analysis on sea trial experimental data,at the range of 3 km and higher SNR,error of location can be controlled within5 %. The effectiveness of the algorithm is verified.
