混频技术测量单次脉冲微波频率的实验研究
-
摘要: 介绍了用混频技术测量单次脉冲微波频率的方法,用50ns、5GHz的单次脉冲微波对混频系统进行了实验研究。目前, 已用此技术测量了虚阴极振荡高功率微波锁频产生的单次微波的频率,并对混频输出的中频信号进行快速傅里叶变换(FFT),得到单次脉冲微波的3dB带宽。Abstract: In this paper a method of usingheterodyne technique to measure frequenciesof single pulse microwave is introducedand heterodyne measurement system isresearched by using 50ns,5GHz singlemicrowave pulse.This technique has beenused to measure single high power microwavepulse frequencies from an OscillatingVirtual Cathod, and the 3dB bandwith ofsingle pulse microwave can been obtainedby Fast Fourier T
