Author Bio(s)

The Pennsylvania State University. He worked at Hughes Aircraft Co., Space and Communications Division, and General Electric from 1982 to 1986 designing RF, microwave and MMW low noise amplifiers, mixers, and filters. He was Present and CEO of a startup 1986 to 1992 that focused on automotive radar. He joined M.I.T. Lincoln Laboratory in 1993 and researched ground penetration radar, ballistic missile defense, and active fuse systems until 2001. He designed cellular base station receivers and small cell transceivers at Airvana, Inc. from 2001 to 2012. Since 2012, he has been a Lecturer at the University of Massachusetts, Lowell and is now an Assistant Professor at Kennesaw State University specializing on antenna design, radar systems, and embedded systems. His research topics are ultra-low noise techniques, crest factor reduction, and the Internet of Things. He is now a senior research engineer at Georgia Tech Research Institute.

interferometry is used in many fields using all frequencies of the electromagnetic spectrum and sound waves. In this study, data was collected from an FMCW radar is used at multiple heights above a flat surface on which sat a single retroreflector. These data were post-processed to discover the signal obtained from the target and then the phase form the radar at multiple locations was compared. Using the known geometry and measured phase, we find the interferometry is possible using a freerunning radar under certain geometric conditions.
