Abstract
Ultra-wideband (UWB) signals and systems have been actively investigated
over the past decade for both medical and industrial radar applications. Recent
UWB radars, capable of measuring distance have been investigated most since
only time information needs to be recovered. Targeted applications include
object detection, collision avoidance in car radar or vital signs monitoring. For
high accuracy in advanced applications, it is however needed to sample the
entire UWB pulse directly instead of only performing energy detection since
the former signal has more information about the target besides its location.
This allows a visualization of the inside of objects and exploit the true benefit
of electromagnetic (EM) imaging. For instance, in the application of breast
cancer detection, this would reveal more information of the tumor and enhance
dielectric contrast. In this work, the proposed application of remotely sensing
the effect of radiation is investigated by proof-of-concept measurements.
For communication purposes, UWB channel models are widely investigated in
terms of bit error rate (BER). For radar applications, few models are available to
derive hardware specifications and analyze the impact of different error sources.
In this PhD we developed hardware for UWB based remote sensing with a focus on skin dosimetry.
