Millimeter-wave/THz FMCW radar techniques for sensing applications
2016
Millimeter-wave and terahertz continuous-wave radar systems have been used to measure physiological signatures for
biometric applications and for a variety of non-destructive evaluation applications, such as the detection of defects in
materials. Sensing strategies for the simplest homodyne systems, such as a Michelson Interferometer, can be enhanced
by using Frequency Modulated Continuous Wave (FMCW) techniques. This allows multiple objects or surfaces to be
range resolved while monitoring the phase of the signal in a particular range bin. We will discuss the latest
developments in several studies aimed at demonstrating how FMCW techniques can enhance mmW/THz sensing
applications.
