曲线匹配法在雷达动态标校中的应用

Applications of a curve matching method in radar dynamic calibration

雷达系统动态标校中,测量数据与真值之间一般通过记录时戳的匹配来计算测量值与真值的误差,从而进行雷达系统误差修正。时间匹配法在数据时戳精度较差时存在一定偏差,时戳精度越差,偏差越大。本文提出一种基于曲线匹配的方法,能忽略时戳误差的影响,并对比了两种方法的差异和优缺点,为雷达系统动态标校提供了一种精确、可行的数据匹配计算方法。

The errors between the measured and true values are generally computed through recording the matching of the time stamps to do the error correction in the dynamic calibration of radar system. Certain deviations occur when the accuracy of the time stamps is very low through the time matching method. The lower the accuracy of the time stamps is, the bigger the deviations are. Therefore, a curve matching method is proposed, which can neglect the effects of the errors of the time stamps. Besides, with the differences, advantages and disadvantages compared between the two methods, a precise, feasible data matching computation method is provided for the dynamic calibration of radar system.
