摘要: 为了使鱼雷更好地识别潜艇结构, 从而有效区分潜艇和声诱饵, 提出了一种基于分布式目标建模的潜艇目标识别方法。该方法在分布式目标建模理论的基础上, 建立了潜艇分布式目标模型, 并把分布式信号参数估计(DSPE)方法应用到潜艇分布式模型方位估计中, 同时利用平面阵进行了计算机仿真, 得到了潜艇回波的3D方位谱。仿真结果表明, 该方法能很好的对潜艇结构进行识别, 有助于鱼雷实施正确的攻击。Abstract: A submarine target recognition method for a torpedo is proposed based on the distributed object modeling to distinguish submarine from acoustic decoy. On the basis of the modeling theory of distributed object, a distributed object model of submarine is established, and the distributed signal parameter estimator(DSPE) is applied to direction of arri-val(DOA) estimation of the submarine distributed model. Simulations are carried out by means of the plane array, and the 3D orientation spectrums of submarine echo are obtained. Simulation results show that the present method can ef-fectively identify submarine structure for correct torpedo attack against target.
