【摘要】 针对一类波束控制起爆的引战系统,讨论了基于α-β滤波算法对导引头测量信息进行数据处理和最小二乘自适应滤波算法对预测起爆角进行二次滤波平滑的方法。从仿真结果分析,α-β滤波后得到的起爆参数可以满足精度要求,但对交会条件以及测量信息的精度等要求较高,对其用最小二乘滤波算法进行二次滤波平滑后,起爆角估计精度得到明显提高。更多还原

【Abstract】 In this paper,the process of information provided by seeker with α-β filter arithmetic and the filter smoothness to the forecast burst angle through adaptive recursive least squares method is studied for the missile fuze system of beam controlled burst. From the simulation,the better burst angle is got using RLS filter arithmetic based on α-β method which meet the burst angle estimation requirement in precision with difficulty to select crash velocity,angle tolerance,and value β.更多还原
