火箭自导深弹空中段关键指标研究

Study on Air Key Indicator of Rocket Homing Depth Charge

依据火箭自导深弹的组成及攻潜过程,建立了仿真模型,在典型条件下,分别采用对目标当前点和对目标提前点两种射击策略,利用蒙特卡罗法仿真分析了弹箭分离高度、入水速度、溅落点散布误差和助飞段平均飞行速度等空中段主要指标对发现概率的影响。仿真结果表明:溅落点散布误差和助飞段平均飞行速度对发现概率影响显著,为火箭自导深弹空中段关键指标;溅落点散布误差控制在200m以内,助飞段平均飞行速度高于250m/s时,具有较高的发现概率。

Some relevant simulation models were established based on the composition and anti-sub process of rocket homing depth charge. In allusion to present /predicated point attacking program,Simulated the influence of the air main indicator on detecting probability with Monte-Carlo under typical conditions. The results show that falling dispersion error and air average velocity are air key indicators of the weapon; when the falling dispersion error is no more than 200m and the air average velocity is beyond 250m /s,the detecting probability holds a high level.
