摘　　要：将时域天线组成阵列是改善超宽带雷达技术性能一条行之有效的途径;研究时域天线阵辐射或接收的波形变换和畸变规律,是十分必要的;利用虚拟仪器技术,采用LabView软件平台,使用模块化设计思想,实现一套基于示波器和转台协调工作的时域天线阵自动测试系统的设计;通过对天线阵测试结果进行分析,并与FDTD的仿真结果进行对比,得出关于时域天线阵有价值的结论。Using the time domain antenna array is very helpful for improving the performance of the ultra wideband radar. It is very necessary to study the law of transmitting and receiving of the antenna array. Using the technology of virtual instrument adopting the soft ware kit of the LabView, and using the idea of module design, we construct the auto measurement system for time domain antenna array based on an oscillograph and a rotation table working harmoniously. Analyzing the test data, and comparing the results with the simulation result from FDTD, we get the valuable conclusions about the time domain antenna array.
