对防空反导雷达系统低角跟踪的多路径误差模型进行验证是检验和评估雷达系统仿真模型有效性的重要方面。对多路径误差进行了分析,利用小波滤波方法和经验模式分解方法从实测数据中提取多路径误差,使用Theil不等式系数、相关系数和小波系数3种方法对仿真结果进行了验证。通过对模型验证结果的分析,表明利用滤波结果进行模型验证更加合理,为评估防空反导雷达系统仿真模型提供了有效手段。

The validation to the multipath error model of low-angle tracking for air defence and antimissile radar system is an important aspect to test and evaluate the validity of radar system simulation model.This paper analyzes the multipath error,extracts the multipath error from tested data by means of wavelet filtering method and empirical mode decomposition（EMD） method,validates the simulation result by using three methods：Theil inequality coefficient,correlation coefficient and wavelet coefficient.The analysis of model validation result indicates that using the filtering result to perform model validation is more reasonable,which presents effective means for evaluating simulation model of air defence and anti-missile radar system.
