Measuring the carrier frequency of single short-duration MWradio-wave pulses

A new method for measuring the carrier frequency of single microwave (MW) radiowave pulse is described, which is based on its transduction to a series of echo pulses using a transversal filter. The analysis of the radio-wave pulses exhibiting constant carrier frequency or frequency modulation is shown to be both theoretically and experimentally feasible with the help of a bulk acoustic-wave delay line. A frequency meter has been developed for single short-duration 2.5-10.5-GHz radiowave pulses, which was demonstrated to be operative under strong radio-interference conditions
