闭环校射中雷达跟踪弹迹的滤波和预测方法

闭环校射武器系统中,要求实时测量弹丸和目标之间的偏差,因此火控雷达要同时完成对弹丸运动和目标运动的跟踪任务,实现对弹丸目标的精确跟踪对火控雷达来说是一个新任务.建立了一种针对此类问题的滤波和预测方法,这种方法充分利用关于弹丸运动规律的已有知识,突破了常规动目标跟踪方法的限制,使滤波和预测误差比常规方法减小数倍,成功地解决了闭环校射武器系统中的一个技术难点.

Predicting and Filtering Algorithm for Projectile Motion Tracking in Closed-loop Fire Control System

Projectile motion tracking is a key issue in modern gun system using close-loop fire control method due to its demand for both high precision and real-time processing.This paper describes a new method about this issue,which can reduce the filtering and prediction error significantly.The new method is based on the introduction of the known trajectory characteristic into the normal motion target tracking theory.
