舰炮火控中滤波和预测的新思路

The New Idea for the Filter and Predication in Shipborne Gun Fire-Control

通过对现有火控中应用的滤波和预测方法的剖析和对火控输入信号及噪音的分析 ,提出了一种新的滤波和预测原理——闭环跟踪滤波原理。采用随动系统原理、误差相消原理和自适应控制原理相结合的方法 ,适合一次或二次运动的目标和噪音频谱大于目标运动频谱 10倍频程以上的情况 ,并能获得既快又精确的目标现在点参数和未来点位置值。

A new filtering principle called close loop tracking and filtering principle is proposed after an- alyzing the current filtering and prediction methods and the signal and noise of fire-control inputs.Servo system principle,error cancelling principle and adaptive control method are applied to the first of second order motive target and the spectral distribution of noise is ten times greater than the motive target's.The presant moving parameters and future position of target can be obtained with quickly convergent response and highly accuracy.
