Noninvasive thermometry using multiple-frequency-band radiometry: A feasibility study

Abstract
The potential use of multiple‐frequency‐band radiometry as a means of noninvasive sensing of one‐dimensional temperature profiles is presented in this communication. The radiative energy transfer equation is solved numerically. Ideal‐condition thermal noise spectra and distributions of received energy, associated with specific temperature‐depth profiles, are presented. Performance characteristics are discussed.
