Recent Experimental Results with LASS-Based Ultra-Wideband Radar Systems

Abstract

This paper describes the design and experimental performance of an ultra-wideband (UWB) demonstrator source/antenna system. The system is composed of the following elements: 1) a low impedance (<1/4 omega) source based on Light Activated Silicon Switches (LASS) operating in the 50 MW range with a rise-time of less than 100 ps, 2) a rise-time conserving transformer with an impedance ratio in excess of 200:1 and a power efficiency of greater than 50%, 3) a TEM antenna, 4) a diode laser pumped laser system for light activation, and 5) a receiver for detecting the radiated waveforms.
