| 摘 要： | 为提高微波空间合成的效率和经济性,提出了一种基于抛物面天线阵的空间功率合成技术。采用抛物面天线作为天线阵列的基本辐射单元，综合考虑空间功率合成效率和相位一致性之间的关系，通过数值分析和理论公式对比得出：合成效率只与单元的幅度和相位有关，与合成单元的数量无关。对阵列单元、天线阵的合成效率进行了软件仿真，得到的合成效率约为92%。结合实验结果，分析了影响合成效率的因素和提高合成效率的方法。

| Abstract: | The spatial power-combination, adopting parabolic antennas as the array cells, has been studied, considering the relation between the spatial power-combination efficiency and the amplitude error and phase error of antenna cells. The results of numerical theoretical analyses and show that the efficiency of spatial power-combination is only related with the amplitude error and phase error of antenna cells only. The simulation on the antenna units and the antenna array shows a spatial power-combination efficiency about 92%.The influencing factors and the improvement methods of the efficiency have been presented． |
