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