反潜直升机搜索常规潜艇概率分析与建模

摘要

常规潜艇在对水面舰艇进行攻击后其发射阵位点很可能会暴露,水面舰艇会利用舰载直升机对潜艇进行搜索和攻击.常规潜艇为了能在尽可能短的时间内脱离发射阵位点,其脱离速度在开始的一段时间内采用高速,并保持恒定.但由于常规潜艇受到电池能量的限制,在整个脱离过程中其速度不可能始终保持恒定高速,脱离速度会随着时间的延长而降低.反潜直升机从水面舰艇飞到潜艇发射阵位点需要一定的时间,从而产生时延.在这段时延内,潜艇会采用恒定高速脱离.因此,反潜直升机的时延对潜艇位置圆会产生影响,相应的探测概率也会变化.%After a diesel-electric submarine attacks a surface vessel, the position of submarine has been revealled probably. The helicopter on the surface vessel will search and attack the diesel-electric submarine. In order to leaving the position in the shortest time, the diesel-electric submarine has to adopt and keep the highest speed at the beginning. The constraint imposed by the remaining charge of its battery determines that the speed of this kind of submarine is not the highest always. With the time extending, the escape speed of the submarine will become slower. The helicopter needs some time to fly above the submarine's attack position dot. In the time the submarine will adopt the highest speed. So, the delay time of helicopter will affect the submarine position circle and the probability of detects.
