摘　　要：以减轻索网天线反枕效应以及提高伞状天线型面精度及误差均匀性为目的,提出了一种伞状天线新型索网拓扑结构。首先进行索网索段划分,得出一种伞状天线新型拓扑构型;其次从索网精度计算方法出发,采用高斯—勒让德积分方法进行伞状天线索网型面精度计算;最后通过算例对新型索网构型进行对比分析,得到该新构型对于提高天线型面精度以及改善误差分布均匀性具有重要意义。In order to reduce the back-pillow effect of cable-net antenna and improve the accuracy and error uniformity of umbrella antenna surface,a new cable-net topology of umbrella antenna is proposed.Firstly,the cable network segment is divided to obtain a new topological configuration of umbrella antenna.Secondly,starting from the cable net accuracy calculation method,the Gauss-Legendre integral method is used to calculate the accuracy of the umbrella sky clue network surface method.Finally,the new cab-net configuration is compared and analyzed by example,and it is of great significance to improve the accuracy of the antenna surface and improve the uniformity of error distribution.
