| Abstract: | The paper designs a high power ultra-wideband(UWB) radiation source, which consists of high voltage pulsed power supply, pulse forming line, impedance transformation unit, transmission line, etc. The parameters of all the parts are analyzed and matched. And an experimental set is built accordingly. An over 30 GW pulse with duration of 1.6 ns can be obtained on the 2.7 Ω pulse forming line. Through Cassegrain dual reflector antenna, the effective isotropic radiated power exceeds 2×1012 W, the radiated field factor exceeds 8 MV, and the 3 dB widths of power of E- and H-plane of radiation are 2.35° and 2.27°, respectively. |
