摘要
本文用矩量法、物理光学法及消奇点技术,对大型平板缝隙阵列天线的散射进行了研究,计算了典型阵列的雷达截面积(RCS),并进行了实验验证,两者趋势基本一致。本文计算结果表明,平板对散射场的贡献(结构项)远大于缝隙对散射场的贡献(模式项)。
The back scattering from a planar slot-array antenna is studied by the moment method and the technique of singularity elimination of the field integral. The scattering field from the conducting plane is computed by physical optics. Theoretical results of radar cross section (RCS) are compared with the measured ones, and good agreement is achieved. It is shown from this investigation that the scattering field contribution from the conducting plane is much greater than that from the slots.
