摘　　要：用矩量法计算了３种箔条云团模型的后向雷达散射截面积。计算结果表明平均间距较大时（大于２λ）互耦对ＲＣＳ影响不大，后向散射截面积的概率分布无论考虑互耦与否都满足指数分布，只是其数学期望有所不同。The backscattering cross sections of three kinds of chaff clouds models are computed by the Method of Moment(MM). The results show that multi couple has very little effect on RCS when the average spacing is larger than 2λ . And the cumulative probability function of backscattering cross section with multi couple can be expressed by an exponential distribution just like the condition without multi couple, except for the only difference that the expectation should be modified.
