  This paper aims at presenting the basic functionality of a radar platform for
real-time monitoring of displacement and vibration. The real time capabilities
make the radar platform useful when live monitoring of targets is required. The
system is based on the RF analog front-end of an USRP, and the range
compression (time-domain cross-correlation) is implemented on the FPGA included
in the USRP. Further processing is performed on the host computer to plot real
time range profiles, displacements, vibration frequencies spectra and
spectrograms (waterfall plots) for long term monitoring. The system is
currently in experimental form and the present paper aims at proving its
functionality. The precision of this system is estimated at 0.6 mm for
displacement measurements and 1.8 mm for vibration amplitude measurements.
