Simulation Analysis on Two Methods for Incoming Torpedo Trajectory Prediction

对来袭鱼雷运动要素的掌握是水面舰艇制定鱼雷防御策略的重要依据。文中首先围绕鱼雷防御态势特征,选择以"两方位一距离一速度"模型为基础分析鱼雷运动要素的解算原理,并给出这种实际弹道预测法的仿真说明。其次,分别归纳了潜射直航鱼雷、声自导鱼雷、尾流自导鱼雷的弹道预测模型以及线导鱼雷的线导导引模型,并给出这种似然弹道预测法的仿真说明。最后,围绕上述2种弹道预测方法进行了仿真比对,从中提取出鱼雷弹道散布的综合求解规律。结果证明,综合运用2种弹道预测法能够有效提高鱼雷弹道散布分析的准确性和客观性,可为水面舰艇的鱼雷防御决策提供参考。

In order to plan a sufficient defense strategy for surface ships,it is important to consider the threat of torpedoes.By obtaining incoming torpedo motion parameters,the trajectory of an incoming torpedo can be predicted.First,according to torpedo defense characteristics,the principle of solving target motion parameters is analyzed based on a two-bearings,one-distance,and one-velocity(2 B1 D1 V)model.The algorithm simulation of the actual trajectory prediction method is described and discussed.And then,the azimuth guidance model for a wire-guided torpedo and the trajectory prediction models for a straight-running torpedo,acoustic-homing torpedo,and wake-homing torpedo are generalized.The algorithm simulation of the estimated trajectory prediction method is also described and discussed.Finally,synthetic environment simulations based on two types of trajectory algorithms are compared,and solutions of torpedo trajectory dispersion are extracted.The accuracy and objectivity of torpedo trajectory dispersion prediction is improved,and the torpedo defense response of a surface ship can be supported by the synthetic application of either type of trajectory algorithm.
