卫星成形反射面天线波束赋形的研究
A Study of Contoured Beam of Satellite Shaped Reflector Antenna
【摘要】 采用单馈成形反射面天线,将天线口面分为多个栅格,通过优化栅格的场的相位分布对中国版图进行波束赋形。在优化过程中附加了相位限制条件,以保证反射面的表面连续,并与阵馈抛物反射面天线的赋形效果作了分析比较,说明单馈成形反射面天线在波束赋形中是可取的,该单馈成形反射面天线有其实用价值。
【Abstract】 The optimization technique of the phase distribution of the apterture plane grid field is presented to contour China map by using shaped reflector with a single feed.In order to avoid the discontinuity of the reflector surface,a restraint is defined in the process of optimization.The contoured result of this antenna contrasted with that of array fed reflector proves that shaped reflector with a single feed is desirable and applicable for contoured beam.
