摘    要:雷达信号模型是雷达系统仿真的重要组成部分,因此雷达信号模型验证在系统可信性分析中具有重要意义。采用经典谱估计和最大熵谱估计两种方法对仿真产生的两组雷达信号进行谱估计,提出了利用相关系数方法在频域对模型进行验证,对比分析了两种方法的优缺点,并对某雷达仿真系统与某次试验采集得到的数据进行了验证,表明此雷达仿真系统具有较高的可信度。

关 键 词:模型验证  谱估计  雷达信号模型  相关系数

Abstract:Radar signal model is an important part of radar system simulation, so its validation has an important meaning in the analysis of system creditability. Two kinds of methods including the classical spectral estimation and the maximum entropy spectral estimation are applied to spectrum estimation of two groups of radar signal produced by simulation. Correlation coefficient method is proposed for model validation in frequency domain. Comparative analysis result about advantage and disadvantage of these two kinds of methods is given. Data from some radar simulation system and experiment is validated with this method, which indicates relatively high reliability on the radar simulation system.
Keywords:model validation  spectrum estimation  radar signal model  correlation coefficient
