摘要
如何评价雷达相对系统误差估值的有效性是雷达校准过程中一个亟待解决的问题。本文借助信息论中相对熵的概念,通过计算次站观测航迹线系统误差修正前后与主站观测航迹线的相对熵,提出了次站雷达相对系统误差估值有效性评价指标和计算方法,并进行了演示验证。该方法有助于提高雷达检飞、数据校准方法选择和雷达相对系统误差估值表计算过程中对系统误差估值评价的科学性、准确性和可操作性,同时对改进多雷达航迹关联算法具有一定的借鉴意义。
How to evaluate the effectiveness of relative system error estimation of radar is an urgent problem in radar calibration.Based on the concept of relative entropy in information theory,the effectiveness evaluation index and the computing method of relative system error of sub-station radar are established in this paper by calculating the relative entropy between observation tracks of sub-station before and after system error correction and observation track of the master station.And demonstration and verification are also presented.This method can improve the scientificalness,accuracy,and operability of the system error evaluation in the process of radar flight test,data calibration method selection and calculation of radar relative system error evaluation table.At the same time,it is useful for improving multi-radar track correction algorithm.
