low power uwb cmos radar sensors
p 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 . p 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 .
