Short-Range FMCW Radar Platform for Millimetric Displacements Measurement

Résumé

A frequency modulated continuous wave (FMCW) radar platform for millimetric displacement measurements of short-range targets is presented in this paper. The platform's transceiver is based on a heterodyne architecture because the beat frequency is relatively small for short-range targets and it can be placed in the frequency range influenced by the specific homodyne architecture problems: DC offset, self-mixing and 1/f noise. The platform's displacement measurement capability was tested on range profiles and SAR images acquired for various targets. The displacements were computed from the interferometric phase. The displacements errors were situated below 0.1 mm for metallic bar targets placed at a few meters from the radar.
