摘　　要：推导了箔条雷达散射截面(RCS)的计算公式及其衍生的公式;基于矩量法和伽略金法,计算和比较了箔条散射与振子辐射的感应电流分布和远场方向图的差异,讨论了箔条空中姿态对感应电流分布及远场方向图的影响;给出了单站散射和双站散射情形单根箔条平均有效雷达截面的定义和计算公式.The formula of radar cross section （RCS） of chaff and the derived formulas are educed. -Based on the moment method and the Galer Kin method, the differences between the induction current distributions of chaff scatting and Dipole radiation, and the far-field patterns are calculated and compared, and the influences of the attitude of chaff in space on induction current distributions and far-field patterns are discussed. Lastly, the definition and formulas of average effective RCS of one single chaff in the single-station and bi-station scattering conditions are given.
