单次短脉冲微波频率分析系统环流波导色散线
-
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，为单次短脉冲微波频率分析提供了一种有效的手段。Abstract: 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．
