We present an impulse ultra-wideband (UWB) sensor and demonstrate its sensing capability through various tests. The sensor, consisting of transmitter, receiver and antennas integrated together in a single package, is capable of transmitting impulse signals varying from 450 to 1170 ps and detecting signals up to 5.5 GHz. It has a range resolution of about 1 inch. The system can vary the transmitting pulse duration, thus effectively simulating multiple UWB systems working together consecutively. 2010 Copyright SPIE - The International Society for Optical Engineering.
