UWB impulse radiation source with integrated optoelectronic generator

Abstract

This paper presents an innovative design of an Ultra Wide-Band (UWB) impulse radiation source. The transmitting system is composed of an UWB antenna with an integrated optoelectronic generator, which is able to feed the system with appropriate waveforms, a pulsed high voltage source, and an optical command system. The radiation source is the elementary part of a forthcoming short-range UWB Radar with autonomous scanning capability. In this paper, we present in detail the necessary subsystems required to design the elementary radiation source. Measurements have been performed to validate the proposed radiation source and this offers a mathematical method of calculation to trace back to the radiated field at 1 m.
