A RING OF WAVEGUIDE DISPERSIVE LINE FOR SINGLE SHORT PULSE MICROWAVE FREQUENCY ANALYSIS

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.
