Measurement of Parameters of X-Band High-Power Microwave Superradiative Pulses

This paper describes the waveguide antenna, the detector based on the thermionic microwave diode, and the alcohol-filled calorimeter developed at the Institute of High Current Electronics. The techniques were used to measure parameters of X-band microwave pulses with a peak power of approximately 1 GW and a pulse length from 0.7 to 1 ns. The error of the peak power measurement was about 15%.
