摘　　要：为了在工程上实现远距离、低信噪比条件下对水下目标进行有效检测与方位的精确估计,提出了基于互谱时延估计方法和三角定位原理的被动目标声定位方法和区域控制方法,并通过仿真试验、消声水池试验和实船数据验证,结果表明,所提方法简单易行、可操作性强,具有较好的工程应用前景。A passive acoustic localization method and a district control method are proposed based on cross-spectrum time-delay estimation method and principle of triangulation localization in order to effectively detect an underwater target and accurately estimate its direction under long distance and low signal-to-noise ratio（SNR）, and are verified by simulation, anechoic tank test and the data of real ship. The results show that the proposed methods are simple and operable, and have a good engineering application prospects.
