反鱼雷鱼雷拦截弹道及拦截概率

通过分析反鱼雷鱼雷的2种不同拦截弹道，建立了迎面逆弹道拦截和直接直线拦截方案的数学模型，讨论了来袭鱼雷方位角和反鱼雷鱼雷发射角之间的关系，采用蒙特卡罗法，仿真计算了本舰对来袭鱼雷的测距和测向误差对反鱼雷鱼雷拦截目标概率的影响，同时讨论了拦截弹道与反鱼雷鱼雷性能的关系。结论表明，迎面逆弹道拦截方式具有更高的拦截概率；对来袭目标实现准确定位能有效的提高反鱼雷鱼雷对来袭目标的拦截概率；增加反鱼雷鱼雷的自导探测距离和搜索扇面角能有效提高对来袭鱼雷的拦截概率。

Intercept Trajectory and Intercept Probability of Anti-Torpedo Torpedo

Based on the analysis of two intercept trajectories of anti-torpedo torpedo （ATT）, mathematical models of converse trajectory and direct trajectory were established. The relationship between the azimuth of incoming torpedo and the launching angle of ATT was discussed. The influence of ship＇s course and distance measurement error of incoming torpedo on the intercept probability of ATT was simulated and calculated by Monte-Carlo method. The relation between the intercept trajectory and the performance of ATT was also discussed. Simulation results indicate that converse trajectory has a higher intercept probability. Accurate positioning of the incoming torpedo can effectively improve the intercept probability of ATT. And increasing homing detection distance and search sector angle can also enhance the intercept probability of ATT.
