Ultra-wideband (UWB) systems are capable of a precise object positioning and tracking in three dimensions thanks to their inherent fine spatial resolution. Thanks to their inherent immunity to a multipath propagation, they are superior over any other technology operating in narrowband. That feature makes them ideal candidates for systems operating in a highly cluttered environment e.g. typical office, warehouse etc. The UWB systems applications range from high speed, short range data links to UWB radar.

Researchers in Centre for Adaptive Wireless Systems are currently developing UWB radar based system that would allow positioning and tracking of the objects with a high accuracy within a complex environment. This technology has a potential of extending GPS-like positioning capability within indoor environments. Furthermore, one of the objectives of the project is aiming at providing a unique identification capability with passive means. The experiments conducted proved that small metallic objects can be successfully tracked in 2 dimensions with a high spatial accuracy.

The system consists of a number of UWB antennas that are connected to a single UWB receiver. The data from the receiver is sent to a standard PC for a further processing and visualization.
