摘要

针对天线罩误差斜率问题

建立了视线角速度估计模型

基于结构随机跳变系统最优滤波理论

提出了一种新的天线罩误差斜率修正的视线角速度估计算法;考虑算法的实时性和快速性

同时推导了两种简化算法.仿真结果表明天线罩误差斜率在较大范围内随机变化时

3种算法都能实时地对天线罩误差进行修正

能够准确地估计视线角速度

明显减小导弹脱靶量.但3种算法都具有不同的计算复杂度和精度

在实际应用中可根据计算时间和内存大小不同的需要选择合适的算法

以满足工程需要.

Abstract

An estimate model of line of sight(LOS) angular velocity aimed at radome error slope was presented.Based on the optimal filtering theory of structure stochastic jump system

a new algorithm for estimating LOS and correcting the radome error was proposed.At the same time

other two simple algorithms were deduced.The results of simulations show that when radome error slope stochastically changes in a wide range

all above three algorithms can correct the radome error

precisely estimate LOS angular velocity and reduce the missing distance obviously.But three algorithms are with different complexity and precision.According to different requirements of computing time and memory size in the application

the appropriate algorithm is selected to meet all the conditions in the project.
