Development of high power UWB pulse radiation source

A high power UWB pulse radiation source was developed, which was composed of a repetition rate high power pulse source, a wideband pulse producing setup and a wideband pulse emission antenna. The parameters of the high power UWB pulse radiation source were that the output voltage of the pulse source was 600 kV, the repetition rate 100 Hz, the pulse output peak power 10 GW, the pulse duration 1.2 ns, the radiation peak electric-field of the IRA 16.1 kV/m, and the equivalent power 0.42×1012 W at the distance of 220 m on the principal axis of the IRA. The half-power width of E-side of the radiation was at 8° and that of H-side was at 9°.
