THE STUDY OF CONTOURED BEAM OF SATELLITE REFLECTOR ANTENNA

摘要: 衛(wèi)星波束賦形天線普遍采用陣饋拋物反射面天線和單饋成形反射面天線。針對前者陣饋和后者反射面表面形狀復(fù)雜的特點，本文分別采用了遺傳算法和共軛梯度法對這兩種天線進行了優(yōu)化，并獲得了中國版圖的波束賦形，說明上述算法在衛(wèi)星反射面天線波束賦形優(yōu)化中是有效的。

Abstract: Array-fed parabolic reflector and shaped reflector with a single feed are usually used to be contoured beam satellite antenna. In the paper, in accordance with the feature of array feeds of the former and the complex reflector surface shape of the latter, genetic algorithms and conjugate gradient method are chosen to optimize this two kinds of antenna to contour China map respectively, which proves that the aigorithms are effective in the optimization of contoured beam of satellite reflector antenna. -
