Paper Abstract

Coherence in radiometry, or the radiometry of radiation in any state of coherence has had a short and checkered history. So short, in fact, that the very subject needs definition, elucidation, and bounds. In this article I would like to outline several specific areas in which coherence theory of some sort and radiometry come into contact. The twain meet and in several different ways. The first has to do with the noise equivalent power (NEP) of thermal and photon detectors. The second has to do with the theory of partial coherence and extended definitions of radiance, radiant emittance, radiant intensity, etc. The third deals with the conjunction of radar theory and the measurement of "coherent" returns from specific objects.
