摘要：

三元组射频仿真是电子系统进行外场试验前的必要步骤,仿真的有效性取决于电子系统在室内仿真与外场试验下的响应一致性。研究了耦合效应对三元组射频仿真的影响。通过理论分析与全波电磁计算,分析了发射端三元组单元间的耦合、接收〖JP3〗端单元间耦合对仿真的影响。结果表明,当接收端方向图在三元组邻域内均匀时,发射端的单元间耦合可以忽略;当接收端各支路的天线之间耦合参数与电磁波照射方向无关时,接收端耦合对射频仿真无影响。基于文中参数,发射端耦合、接收端耦合造成的仿真误差分别低于总仿真误差两个数量级、一个数量级。

Abstract:

Radio frequency simulation system (RFSS) based on the three unit array (TUA) is necessary for the electronics system research and development. The validity of the RFSS testing is determined by the consistency between the electronics system’s response in the RFSS testing and the electronics system’s response in the outfield testing. This paper studies the coupling effects on the RFSS. The effects of the coupling among transmitting units and the coupling among receiving units are analyzed through theoretical analysis and numerical computation. The results show that, if the receiving antenna’s pattern is flat in the TUA region, then the coupling among transmitting units can be ignored; if the coupling parameter among the receiving antennas is constant for the various incident angles, then the coupling among the receiving antennas can be ignored. Based on the parameters used in the computation, the simulation errors caused by coupling of transmitting units and receiving units are less than 1% and 10% of the total simulation error respectively.
