【摘要】 卫星波束赋形天线普遍采用阵馈抛物反射面天线和单馈成形皮射面天线。针对前者阵馈和后者反射面表面形状复杂的特点,本文分别采用了遗传算法和共轭梯度法对这两种天线进行了优化,并获得了中国版图的波束赋形,说明上述算法在卫星反射面天线波束赋形优化中是有效的。更多还原

【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 these two kinds of antennas to contour China map respectively, which proves that the algorithms are effective in the optimization of contoured beam of satellite reflector antenna.更多还原
