摘　　要：本文针对大功率合成器在轨长寿命工作的高可靠性要求,首先给出了两种环备份方法,然后,根据功率合成和天线波束形成的等相位要求,提出了基于输入输出总路径等长的电缆、波导设计方法。计算机仿真试验验证了两种环备份方法的电缆、波导设计方法的有效性,该方法也可以简化应用于对空间布局不受限,只要求输入、输出路径分别等长的情况。For the high reliability request of long time working in orbit of the spaceborne radar＇s high power combiner, this paper firstly gave the two kind of cycle-backup methods, and, latterly, according to the equiangular request of the power combining and antenna beamforming, presented the designing method of the cable and wave-guide based on the in-out equal path. The simulation confirmed the validity of the designing method, which also could be applied to the situation of space lay- out unlimited, only asking for in-out equal path.
