Study on the generation of ultra-wideband (UWB) high power microwave

The experimental study of ultra-wideband (UWB) technology. its generation and on-line measurement are presented. An experimental repetitive UWB system is designed, manufactured. and tested. High-pressure spark gap switch and its components, as well as oil spark gap switch are studied experimentally on the system. Experimental results indicate that the system operates at a 200 pps repetitive rate with a stable performance. 100 MW peak power UWB pulses are obtained on the system. Fast-time response: capacitive divider is designed and fabricated. allowing for an accurate measurement of the high power UWB signal. The main issues related to the design of the switch and the UWB signal online measurement are discussed.
