摘　　要：在电子对抗领域,空间功率合成技术因其能够突破功率器件的制约得到强大的干扰功率,已成为研究的热点。介绍了空间功率合成系统的基本原理和主要技术,分析了影响空间功率合成效率的主要因素,通过计算机仿真进一步分析了AWGN信道条件下载波相位误差和包络时延误差对空间功率合成效率的影响,进而分析了信号相干带宽与合成效率的关系,最后根据仿真结果对采用空间功率合成技术的通信对抗系统给出了初步的系统构成,并给出了相位调整和时延调整2个关键模块实现方法。The spatial power-combining technique becomes one of the focuses in electronic countermeasure area, because it can obtain higher power by breaking restricts of power devices, The paper introduces the spatial power-combining technique and analyzes the main factors affecting the combined efficiency, the efficiency of the AWGN environment under the influence of carrier-phase-error and envelope delay error and the relationship of combined efficiency and signal coherent bandwidth. Finally it gives a preliminary system constitution of a communication countermeasures system using the spatial power-combining technique and an implement method of the two key modules of phase regulator and delay regulator.
