摘　　要：针对近场箔条云RCS实测数据使用的局限,提出了一种基于RCS起伏模型的箔条云近场特性实测数据的分析方法。该方法提供了近场箔条云散射特征分析的新思路。开展了箔条云近场动态测量试验,对实测的近场Ku波段的箔条云RCS的概率分布进行了拟合,并对分布模型的拟合优度进行了检验。结果表明,在显著性水平为0.05时,该箔条云在Ku波段的动态RCS概率分布服从对数正态分布。Aiming at the limitation of the use of near-field chaff cloud RCS measured data,an analytical method for near-field measurement data of chaff cloud cluster based on RCS fluctuation model was proposed.This method provided a new way to analyze the scattering characteristics of chaff cloud in the near field.Then,the near-field dynamic test of chaff cloud was carried out.The probability distribution of RCS of chaff cloud in Ku band of near field was fitted.The goodness of fit of the distribution model was tested.The results showed that the dynamic RCS probability distribution of the chaff cloud in the Ku band obeyed the lognormal distribution when the significance level was 0.05.
