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 dG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。

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 dG,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 within 5%. The effectiveness of the algorithm is verified.
