主动攻击水雷正横攻击首次捕获目标概率计算方法

Research on the probability calculation of first target locked in abeam attack of homing mine

正横点是指过水雷布放点在水面的投影做目标航迹的垂线,与目标航迹的交点。主动攻击水雷正横攻击是指当目标到达封锁区域内的正横点时,被动探测系统进行目标锁定跟踪,并预测目标航迹一定距离后再进行攻击的一种攻击决策方式。本文在分析主动攻击水雷正横攻击方式的基础上,提出了使战斗载荷首次捕获目标概率最大的锁定跟踪距离计算方法,并据此推导出该方式的概率计算模型。最后对模型进行了数值仿真分析。

The abeam point in this paper refers to a point on the target＇s trajectory, and the line over this point and the surface projected point of the mine is vertical to the target＇s trajectory. When the target crosses the abeam point in the blockaded area, the passive detecting system locks and tracks the target, after the evaluation and prediction of the target＇s movement, the mine launches the attack. This approach is called the abeam attack and is discussed in this paper. The various ways of the abeam attack are first presented, the approach to calculate the locked and tracked length which has the maximal probability to detect the target is derived. Based on these results, a probability calculation model of this approach has been got. Numerical simulations of this model have been done in the end.
