自导鱼雷区域射击法研究

针对如何有效打击只能确定初始位置及运动方向的匀速直航潜艇，提出了自导鱼雷对匀速直航潜艇射击的区域射击法，即采用与匀速直航潜艇运动方向相同的固定提前角进行射击，建立了鱼雷与潜艇的区域射击法对抗模型，通过实例计算分析了固定提前角的确定方法，验证了区域射击法对中近距离上向固定方向运动的匀速直航敌潜艇对抗的有效性。仿真结果表明，在500～4000m距离内，对向固定方向运动且速度小于20kn的潜艇，采用7^o～15^o的固定提前角射击，对潜艇的命中概率可达到0．8。

Area Shooting Method of Homing Torpedo

In order to effectively shoot homing torpedo at a submarine with available original position and course, this paper puts forward a concept of area shooting method of homing torpedo in which the fixed lead angle along a equal speed straight-running submarine is employed, and subsequently establishes a game model. An example is given to explain the determination of the fixed lead angle, and to verify that this method is effective when shoot homing torpedo at the equal speed straight-running submarine in a close or middle distance. The simulation results show that for the submarine sailing in fixed direction with a speed less than 20 kn, the hit probability is 0.8 within the range of 500 -4 000 m and the fixed lead angles of 7 - 15 degrees.
