摘　　要：介绍了一套天线瞬态特性测试系统,该系统主要由数字采样示波器、控制计算机、极窄脉冲源、转台等组成。分析了测试系统的基本理论,建立了实验装置,并对理论分析所得结果进行了验证。在不需要微波暗室的情况下,能够较为精确地测量出天线的远场特性。A measurement system of antenna transient character was introduced in this paper, which was mainly composed of digital sampling oscilloscope, short pulse generator, control computer, EL/AZ positioner and so on. The basic theory of this system was anaiyzed and the experimental device was founded. Some typical antennas were measured with this system, the experimental results show that it can exactly measure far filed character of antenna without anechoic chamber.

关 键 词：脉冲 瞬态特性 远场测量
