Book Description
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.
