利用窄脉冲技术的天线测量系统

介绍一种利用窄脉冲技术对天线电性能进行测试的设备。该设备不需要传统测试中的信号源发射连续波信号，其发射和接收的均是窄脉冲信号，然后将接收到的窄脉冲信号进行快速傅里叶变换计算出各频率上的幅度相位信息，因而在天线方向图测量时快速高效，而且可以利用时窗技术选取测试主信号，消除多路反射，杂波干扰等信号，故不需要微波暗室也能实现对天线的精确测量。

An antenna measurement system on short- duration pulse technology

It describes an antenna measurement system based on short duration pulse technology. The source antenna transmitting a series of short duration pulse. The antenna did not need test receive this pulse and then make a FFT (Fast Fourier Transform) compute, obtain the radiation pattern at every frequency. At same time, a time window technology is used in this system, it can eliminate echo signal and other jamming signal, so this system doesn't need microwave anechoic rooms, and the test is very efficient and very accurate.
