随着水面舰船侦察能力的提高，面对来袭鱼雷时，舰船通常会采取机动规避行为，针对在主动探测模式下长探测周期间隙获取机动目标运动要素信息缺失导致解算误差较大影响后续导引，以及尾流自导鱼雷攻击机动目标时约束入尾流角度的难题，本文基于信息融合的Singer模型机动目标跟踪算法，解算目标运动要素信息，导引鱼雷瞄准过去某一时刻尾流生存点，在对目标舷别进行判断的基础上加入角度约束计算偏置项，对鱼雷航向进行修正，控制鱼雷以合适的距离和角度进入尾流，从而对导引平台+尾流自导鱼雷进行有效导引。仿真结果表明，在探测信息存在缺失的情况下，无论目标如何机动，本文方法均能将鱼雷以预设定进入距离和角度导入期望的尾流位置。
With the improvement of the detection ability of surface ships, when facing the incoming torpedoes, ships usually take maneuvering evasion behavior, for the lack of information of maneuvering target motion elements obtained during the long detection cycle gap under the active detection mode, which leads to a large solving error affecting the subsequent guidance, as well as the difficult problem of constraining the angle of entering the wake when the wake self-guided torpedo attacks the maneuvering target, this paper is based on the information fusion of the Singer model maneuvering target In this paper, based on the information fusion Singer model maneuvering target tracking algorithm, we solve the target motion element information, guide the torpedo to aim at the survival point of the wake stream at a certain moment in the past, add the angle constraints to calculate the bias term on the basis of the target's gangway judgment, make corrections to the torpedo's heading, and control the torpedo to enter the wake stream at a suitable distance and angle, so as to guide the guidance platform and the wake-stream self-guided torpedo efficiently. The simulation results show that the method can guide the torpedo into the desired wake position at a preset entry distance and angle regardless of the target maneuvering in the absence of detection information.
