In this paper, the setup of a short pulse simulator for susceptibility investigations is presented. This simulator consists of a compact ultrawide-band source and a half impulse radiating antenna. First measurements of the simulator are compared with calculated fields. The application of interest is the generation of an ultrashort pulse with a high electromagnetic field strength.read more

TL;DR: The Impulse Radiating Antenna (IRA) has generated widespread interest for its ability to radiate a broadband pulse as discussed by the authors, which can be used for target discrimination in a cluttered environment (e.g., looking over the ocean), aircraft identification by taking a "FDR" of its major scattering centers, and target location through foliage.

Generation of high-power subnanosecond pulses
TL;DR: In this paper, a series of experiments on studying the operating modes of sub-nanosecond high-pressure gas gaps are presented, and the results of fundamental importance obtained are as follows: repetitive pulse modulators with highly reproducible and tunable parameters have been realized, sub-cond jitters have been achieved for the starting of electrically triggered gas switches, and compact module systems have been created.
