| Summary: | This paper presents the experimental results of a UWB based imaging system. Radio imaging of a room is performed using an imaging technique based upon the angle-of-arrival (AoA) information through the use of a synthetic aperture. These images are actually a visual representation of the multipaths and have the ability to distinguish between temporally stationary and varying components. The paper describes the measurement and signal processing techniques used to acquire the imaging information. This groundwork can be used for UWB indoor radio channel characterisation and also for optimal design of UWB systems that can be used in applications ranging from multipath-resistant communications systems to ground-penetrating radar (GPR) and medical imaging. |
