This paper discusses the RF interferometry at millimeter-wave frequencies for sensing applications and reports the development of a millimeter-wave interferometric sensor operating around 35 GHz. The sensor is completely realized using microwave integrated circuits (MICs) and microwave monolithic integrated circuits (MMICs). It has been used for various sensing including displacement and velocity measurement. The sensor achieves a resolution and maximum error of only 10 m and 27 m, respectively, for displacement sensing and can measure velocity as low as 27.7 mm/s with a resolution about 2.7mm/s. Quick response and accurate sensing, as demonstrated by the developed millimeter-wave interferometric sensor, make the millimeter-wave interferometry attractive for sensing of various civil and mechanical structures. 2014 SPIE.
