对鱼雷目标进行定位跟踪是舰艇反鱼雷的关键，报警声纳能够给出水下鱼雷目标的方位信息，但仅利用方位信息对鱼雷目标进行定位跟踪是不够的。对本水面舰艇舰壳声纳和拖线阵声纳纯方位协同探测可行性进行分析，并对协同探测条件下鱼雷目标定位跟踪算法进行探讨，建立可应用于鱼雷目标定位跟踪的滤波算法模型，对其定位精度进行分析，并与最小二乘算法进行比较，通过仿真比较，最终确定出可用于鱼雷目标定位跟踪的算法模型。

Locating and tracking torpe do is the key to warship anti-torpedo.Torpedo warning sonar can detect noise of incoming torpedo and get the target’s bearing information,but the bearing information is insufficient to locating the torpedo at present.So the feasibility of cooperative detecting torpedo by ship-shell sonar and towed sonar is analyzed,and localization methods are discussed,filter algorithm is established.By simulation,it analyses the locating precision,and compares filter method with least-sum-squared-error method,according as the result,it finally confirms the adaptive method that is fit for locating and tracking torpedo.
