Millimeter-wave Interferometric Sensing

Abstract

Millimeter-wave sensing systems designed for imaging almost always produce inferior images compared to their infrared and visible wavelength counterparts for a variety of fundamental reasons. These reasons include low detector/pixel count, poor signal-to-noise ratio, artifacts introduced by illumination, and issues arising from calibration or scanning schemes. This research effort is intended to address the issue of low-detector-count focal-plane arrays (FPA). Radio astronomers have dealt with this issue for many decades by using interferometry, or coherence imaging. This report details how interferometric imaging techniques can be used in the millimeter-wave regime for terrestrial applications.
