Abstract
Ultra-wideband (UWB) technology can be used in many applications, including radar, communications, and geo-location. In this dissertation, UWB technology is utilized to directly generate sub-nanosecond pulses with more than 1 GHz bandwidth to implement radio detection and ranging (RADAR) for distances up to 5 or 10 metres. This low-cost, rnicropower radiation, short-range radar profiling system consists of the radar circuitry, the data-acquisition subsystem, the signal processing subsystem and the graphical user interface. Additional modules such as a front-end RF amplifier can be integrated into the complete system. The performance was analysed, particularly the circuitry performance and system performance. The capability for detecting metal objects was demonstrated, along with discussion of preliminary "seeing-through-wall" experiments.
