基于虚拟脱靶量预测的准闭环校射方法

针对传统高炮大闭环校射脱靶量不易检测、可校射时间短暂,提出了一种基于虚拟脱靶量预测的准闭环校射方法。首先给出了弹丸双站角度测量的初始状态估计算法;其次,结合外弹道理论建立了一种虚拟等距脱靶量的预测模型,分析了射击校正量的估计方法与准闭环校射方案的实现流程。该方法避免了大闭环校射对脱靶量的直接检测,并提高了高炮闭环校射的时效性。

Research on Quasi Closed Loop Fire Control Based on Virtual Miss Distance Prediction

As the traditional closed loop fire control lacks timeliness,and the miss distance cannot be measured easily,a method for quasi closed loop fire control based on virtual miss distance prediction is proposed in this paper. First,the estimation algorithm of the projectile initial state is given with the angle measurement that provided by double observation stations. Then,a prediction model of virtual miss distance is founded based on exterior ballistic theory. Moreover,the estimation algorithm of shoot emendation and the process of quasi closed fire control are analyzed. It shows that the proposed method can avoid the direct detection of miss distance and improve the timeliness of closed loop fire control.
