摘　　要：采用分域基（分段正弦函数）Ｇａｌｅｒｋｉｎ法计算了多散射单元一体化结构在８ｍｍ和３ｍｍ两个波段的雷达散射截面σ～θ（散射角）曲线．结果表明：由于散射单元间的耦合作用，存在适当的结构形式，其雷达散射截面在毫米波段远大于单一谐振单元的散射效果；而且单元间间隙极小。Based on subsectional bases (sinusoidal bases) with Galerkin method, the σ￣θ curves of RCS of multiple linear scattering units in 8mm and 3mm wavebands were calculated. The results show that, owing to the coupling between scattering units, not only the maximum RCS in MMW band is greater but the scattering efficiency is also higher than that of the single unit.
