| 摘 要： | 分析了箔条云散射特性测量技术,进而开展箔条云外场动态测量实验。对实测箔条云RCS的概率分布进行拟合,并对拟合结果进行检验,同时分析了箔条云散射特性与时间、频率等之间的关系。结果表明,当显著性水平为0.01时,该箔条云在S波段和X波段的动态RCS服从χ2分布;箔条云形成之后,箔条密度随着时间的推移而下降,导致其RCS减小;随着频率升高而波长减小,箔条间互耦效应将减小,箔条云RCS的起伏也将减小。

| Abstract: | The technique for measurement of chaff cloud scattering characteristics was analyzed,then we made experiment on dynamic measurement of chaff cloud. Fittings were carried out to the statistical distribution of chaff's RCS,and the fitting result was tested. The relationship between chaff cloud characteristics and time/frequency was investigated. It is indicated that:1) at evidence level of 0. 01,the chaff's dynamic RCS presents chi-square distribution at S-band and X-band;2) the density of chaff cloud would d... |
