Novel wide-spectrum electromagnetic pulse test system

A novel wide-spectrum electromagnetic pulse test system is designed. This system makes use of all-inductive isolated repetition frequency Marx generator to produce high-voltage pulse which is then fed into broadband antenna for wide-spectrum radiation through bipolar pulse-forming line. Working principle of this generator and forming principle of bipolar pulse are both introduced. By means of experiment, following qualifications of the system is concluded, output pulse voltage 500 kV, front edge 20 ns, repetition frequency 20 Hz, wide spectrum radiation factor 195 kV, center radiation frequency 200 MHz, spectrum width 37%. Test system has compact configuration and flexible operation and has also 360 degree rotation at azimuth radiation and the remote control function.
