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 a 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 to prove its functionality. The precision of this system is estimated (using the 3\u03c3 approximation) at 0.6 mm for displacement measurements and 1.8 mm for vibration amplitude measurements.<\/jats:p>","DOI":"10.3390\/s19010082","type":"journal-article","created":{"date-parts":[[2018,12,27]],"date-time":"2018-12-27T11:29:43Z","timestamp":1545910183000},"page":"82","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Pulse Radar with Field-Programmable Gate Array Range Compression for Real Time Displacement and Vibration Monitoring"],"prefix":"10.3390","volume":"19","author":[{"given":"Mihai-Liviu","family":"Tudose","sequence":"first","affiliation":[{"name":"Research Centre for Spatial Information\u2013CEOSpaceTech, University \u201cPolitehnica\u201d of Bucharest, Bucharest 011061, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrei","family":"Anghel","sequence":"additional","affiliation":[{"name":"Research Centre for Spatial Information\u2013CEOSpaceTech, University \u201cPolitehnica\u201d of Bucharest, Bucharest 011061, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Remus","family":"Cacoveanu","sequence":"additional","affiliation":[{"name":"Research Centre for Spatial Information\u2013CEOSpaceTech, University \u201cPolitehnica\u201d of Bucharest, Bucharest 011061, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihai","family":"Datcu","sequence":"additional","affiliation":[{"name":"Research Centre for Spatial Information\u2013CEOSpaceTech, University \u201cPolitehnica\u201d of Bucharest, Bucharest 011061, Romania"},{"name":"German Aerospace Centre, Remote Sensing Technology Institute, We\u00dfling 82234, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1367","DOI":"10.1109\/7.543858","article-title":"Low observable target motion analysis using amplitude information","volume":"32","author":"Kirubarajan","year":"1996","journal-title":"IEEE Trans.
