| 摘 要： | 通过在混响室的简化三维模型中随机设置激励天线的位置和姿态实现多天线源搅拌因素的引入.与其他方法的对比验证确定利用矩形腔体的电并矢格林函数来仿真电偶极子激励下的电场分布.研究和分析了多天线源搅拌技术对传统混响室工作区域内场分布均匀性的改善作用,结果和理论分析吻合,其性能的提升会受到天线极化和工作频率的影响.

| Abstract: | Multiple-antenna source-stirring was introduced by stochastic position and polarization of transmitting antennas in a simplified three-dimensional Reverberation Chamber(RC)model.The electric field distribution in RC was figured out by means of Electrical Dyadic Green Function,and that method was verified through comparison with other simulation tools.Furthermore,influence of source-stirring on field uniformity was investigated.Results clearly validated the theory analysis,and the multiple-antenna source-sti... |
