Microwave Radiometry of Blackbody Radiation

Abstract

We outline the theoretical formulation of radiometry of the free-space radiation emitted by a blackbody target. Simulation shows a much smaller drop of radiation intensity of a Lambertian source than that of an incoherent source in the near-field region, indicative of a powerful influence produced by the coherence property of the blackbody source. Further, the coupling of the radiation to a radiometer is formulated by the plane-wave spectrum of the radiation field.
