It is indicated that: 1 at evidence level of 0.01, the chaffs dynamic RCS presents chi-square distribution at S-band and X-band; 2 the density of chaff cloud would decrease with time, which will result in lower RCS; and 3 with increasing of frequency and decreasing of wavelength, the coherence effect between different chaffs would get less, which will result in weaker fluctuation.
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χ^2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。
