摘　　要：特殊条件下潜艇可利用双线导鱼雷被动声自导方式对水面目标实施攻击,双线导鱼雷与艇艏综合声纳就构成了一个三基阵被动探测系统。此时依据探测的方位信息,首先根据最小二乘法得到目标位置的初步估计,然后将其作为测量值用于交互多模型算法(IMM)并结合线性卡尔曼滤波(KF),即可实现对机动目标的跟踪,从而有效避免应用非线性估计算法直接进行多基阵方位数据处理过程中存在的各种障碍。仿真结果表明这一算法简单有效、收敛速度快、跟踪精度高。Surface ship could be attacked by submarine with two wire-guided torpedoes simultaneously under passive acoustic mode in certain condition.A three-array detective system was formed by two wire-guided torpedoes as well as the integrated sonar at the bow of submarine.In this paper,the preliminary estimation of target’position was acquired by the least square method based on real-time bearing data acquired by arrays firstly,then the maneuvering target could be tracked when these estimated position data were applied as measured values to Interactive Multiple Models(IMM)algorithm with Kalman Filter(KF),avoiding some problems brought by applying nonlinear estimation algorithms for data fusion directly.The result of simulation shows that the algorithm mentioned in this paper is simple,the speed of convergence is fast,and the precision of tracking is superior.
