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。 Satellite Beam Antennas generally use the feed-fed parabolic reflector antenna and single-fed skin antenna. In view of the former matrix feed-back and the latter’s complex surface shape, the genetic algorithms and the conjugate gradient method are respectively used to optimize the two antennas and get the beamforming in China. Reflector Antenna Beamforming optimization is effective.
