| Abstract | 本发明公开了一种基于电磁散射理论的反射面天线表面误差的反演方法，其整体思路是：首先测量反射面天线反射面板的表面误差，得到表面误差的测试数据，然后根据表面误差的实测数据建立表面误差分形模型，接下来根据分形模型计算表面误差的源项与谱振幅，再根据源项与谱振幅计算得到表面误差的反演模型，最后实现反射面天线表面误差的准确描述。本发明的有益之处在于：根据天线表面的实测数据建立表面误差初始分形模型，确保了反演模型数据来源的准确性；反演过程中根据初始模型计算面板的源项与谱振幅，通过源项和谱振幅得到表面误差的反演模型，确保了反演过程的准确性，为提高反射面面板表面误差描述的精度与效率奠定了基础。 |
