一种火箭助飞鱼雷命中概率实时评估模型

A Real-Time Evaluating Model of RAT’s Hit Probability

摘要:

火箭助飞鱼雷命中概率实时评估结果是指挥决策的重要依据。首先,根据每个节点相对目标距离舷角的不同,构建火箭助飞鱼雷的静态命中概率表；其次,对火箭助飞鱼雷的射击误差区域进行分区,计算每个射击误差子区域对应的入水点落入概率；再次,根据每个射击误差子区域端点相对目标的距离和舷角,调用静态命中概率表计算每个子区域对应的平均命中概率；最后,将每个射击误差子区域的落入概率与该子区域对应的平均命中概率的乘积进行求和,得到火箭助飞鱼雷的实时命中概率。

Abstract:

The real-time evaluating result of hit probability for rocket assisted torpedo(RAT)is an important basis to com. mand and decision-making. Firstly, the RAT’s static hit probability sheet was obtained according to the distance and rela.tive bearing off the target. Secondly, the fire error distribution area was partitioned into some sub-zones, and the droppingprobability into each sub-zone the RAT’s water-entry point may drop was calculated. Thirdly, the average hit probabilityfor each sub-zone was accounted, which was based on its nodes’distance and relative bearing off the target, as well as the static hit probability sheet. Finally, the RAT’s real-time hit probability was the sum of the multiplication of each sub-zone’s dropping probability and its average hit probability.
