摘　　要：针对小型化通信干扰机功率不足的问题,提出了一种任意分散布阵通信干扰机空间功率合成方法,采用无线的方式控制各单元的发射时间和发射相位,在不破坏单个干扰机结构完整性和独立性的前提下进行空间功率合成。分析了相位同步误差、定位误差和导向误差对功率合成效率的影响,给出了合成效率为0.8时系统对相位同步精度、定位精度和导向精度的要求。结果表明,随着各项误差的增加,合成效率不断减小并趋于下限;干扰机群分布半径越大,合成效率对导向误差越敏感。To solve the problem of insufficient power for miniaturized communication jammers,a spatial power synthetic method for random distributed array communication jammers is proposed.The transmission time and transmission phase of each jammer are controlled wirelessly,and in this way,extremely high synthetic power can be achieved using multiple miniaturized jammers without destroying the structure integrity and independence of any single jammer.The effects of phase synchronization error,positioning error and steering error on the power synthetic efficiency are analyzed and the requirements of phase synchronization accuracy,positioning accuracy and steering accuracy are given when the synthetic efficiency is 0.8.The results show that with the increase of each item of error above,the efficiency will decrease continuously and approach to the lower limit,and the larger the distribution radius of the jammer group,the more sensitive the efficiency is to the steering error.
