一种角误差提取相关处理的新方法

Method of Angle Error Extraction in Leading Edge Tracking

针对反射式工作的脉冲雷达在火箭飞行器一二级分离过程中不能稳定跟踪的问题,提出了角误差相关处理的新方法。该方法区别于常规脉冲雷达角度误差的提取方法,在距离前沿跟踪的基础上对角误差进行加权优化相关处理。通过模拟器跟踪试验,特别是对运载火箭一二级分离实际跟踪应用表明,该方法成功解决了雷达对火箭飞行器级间分离过程中连续、稳定跟踪的问题。

The reflex pulse radar can＇t stable track in the process of rocket aircraft first and second stage separation, a new method of angle error extraction is proposed. The method has weighted optimization to the leading edge tracking, which is different from the conventional method. Through the simulator tracking test, especially the application to the rocket first and second stage separation, it sucessfully sovled the problem of radar continuous and stable track the rocket in the stage separation.
