摘要
提出环流波导色散线微波频率分析方法，介绍了环流波导色散线系统设计思想、电路工作原理、主要性能及应用结果。实验应用表明，该系统测频分辨力比相同长度普通色散线提高６倍以上，克服了微波脉宽引起的测频误差，测量误差小于２％，同时能够测量不同频率成份在微波脉冲中的时间分布。
A frequency analysis system for single short microwave pulse which is developed by means of a ring of waveguide dispersive line is described in this paper.The system is characterized by frequency resolution 6 times higher than that of normal dispersive line with the same length.At the same time,the ring of dispersive line is capable of measuring the time-dependence realation for microwave frequency components and avoides uncertain rising from the duration of microwave pulse,making the uncertain is less than 2%.The system has been used successfully in the experimental study of Vircator.
