研究了一种基于实艇靶舷侧阵的末弹道二维跟踪定位模型,给出了鱼雷攻潜过靶部位及水平攻击角的计算方法,分析了测量误差并进行仿真.分析及仿真表明,采用该定位模型,鱼雷攻艇部位的测量精度可达2 m,在艇正横方向大约±60°开角范围内,水平攻击角的测量精度可达2°.在引起攻击角测量误差的各因素中,同步误差和目标深度装订误差影响较大,声速装订误差和基阵变形引起的误差较小.%A two-dimensional underwater acoustic tracking and location model base on the terminal trajectory of broadside array at the submarine target is studied, and the method of measuring intelligent torpedo's attack point and attack angle of submarine target is presented. The result of simulation shows that the measurement accuracy of attack point would better than 2 m, and that of attack angle would better than 2° when the transverse angle less than ±60°. In all measuring errors being discussed, the effect of the synchronization error and the depth of the target is high, while that of the sound velocity binding error and the deformation of the array is small.
