| 摘 要： | 多天线系统的电磁兼容性很大程度上取决于系统内收发天线间的射频能量耦合。天线间耦合度是评估系统级电磁兼容性的重要指标。针对目前传统手工测试的种种弊端，设计了基于射频开关自动切换的天线间耦合度自动测试系统，详细阐述了系统硬件构成、软件的设计思路以及具体的测试流程，使用LabVIEW编写软件控制收发天线对的自动切换，实现自动测量，具有测量误差小，测量便捷等优点。

| Abstract: | The electronic magnetic compatibility （EMC） of complex electronic system depends largely on radio frequency （RF） energy coupling between receive and transfer antennas. Antenna Couple between the system is an important index of the electromagnetic compatibility. Aiming at the shortcomings of the traditional manual testing, the article designs between the antenna couple automatic test system based on the rf automatic switching, and control compilation of antennas automatic switching uses LabVIEW software to realize automatic measurement. The article describes the system design and the realization of the main principles of functional modules. A detailed illumination of the equipment control flow has been also proposed. Feasibility and accuracy of the system has been proven by a large number of practical tests. |
