Low Power UWB CMOS Radar Sensors deals with the problem of designing
low cost CMOS radar sensors. The radar sensor uses UWB signals in order
to obtain a reasonable target separation capability, while maintaining a
maximum signal frequency below 2 GHz. This maximum frequency value is
well within the reach of current CMOS technologies. The use of UWB
signals means that most of the methodologies used in the design of
circuits and systems that process narrow band signals, can no longer be
applied.
Low Power UWB CMOS Radar Sensors provides an analysis between the
interaction of UWB signals, the antennas and the processing circuits.
This analysis leads to some interesting conclusions on the types of
antennas and types of circuits that should be used. A methodology to
compare the noise performance of UWB processing circuits is also
derived. This methodology is used to analyze and design the constituting
circuits of the radar transceiver. In order to validate the design
methodology a CMOS prototype is designed and experimentally evaluated.
