Non-contact rotating machine health status via dual-polarized radar

Abstract

A dual-polarized radar is capable of characterizing a time-varying target and extracting its vibrational spectrum. This work details the concepts of that process in the context of remotely observing the health of multiple electric pumps at a local industrial plant. The efficacy of the approach is demonstrated through a small-scale experiment sensing different vibration signatures of an electric motor with a dual-polarized radar system.
