摘　　要：基于平面波谱散射理论分析金属空间网架桁杆散射场,通过解析法和矩量法解Pocklington方程计算不同长度圆柱桁杆的表面电流分布和散射系数,得出在矩形口面激励下的散射波谱,从而研究了不同长度圆柱桁杆对口面辐射场的扰动作用。结果表明,口面辐射场所受扰动与桁杆长度有较为明显的关系,桁杆的长度越大,对辐射场的扰动也越大。The scattering characteristic of the strut in metal space frame is analyzed based on the plane wave spectrum scattering theory. The surface current distribution and scattering coefficient of the cylinder strut with different lengths are calculated by solving the Pocklington equation with ana- lytical methods and MoM. The Perturbation on the field radiated from the rectanglular aperture by the cylinder strut is studied according to the scattering spectrum. It is presented that the length of strut has a great influence on the radiation field. Longer cylinder strut contributes to greater pertur- bation on the radiation field.
