Abstract :
This paper describes the design and test of a radiating system for impulse-like waveforms. The antenna is a 3.66 meter diameter paraboloidal reflector fed by a pair of conical TEM feed structures. The pulse generator that feeds the TEM structures incorporates an electromagnetic lens to ensure a near-ideal spherical TEM wavelaunch, and a/spl ges/120 kV, /spl sim/100 atm. hydrogen switch operating in burst mode at up to 200 Hz. The antenna radiates a waveform which is the time-derivative of the double exponential [/spl sim/100 ps, 45 nsec 10-90% rise and fall] waveform supplied by the pulser.
