A physically-oriented statistical prediction of sky-noise temperature intercepted by ground Deep-Space antennas has been developed, based on simulations obtained by using a radiative transfer model approaching the electromagnetic propagation in a scattering medium. A model dependent on attenuation, frequency and elevation angle is proposed for describing the atmospheric mean radiative temperature, which relates sky-noise temperature to attenuation. Model validity ranges from X to lower W band for space research allocated bands and for elevations between 10 deg and 90 degrees.

Abstract
A physically-oriented statistical prediction of sky-noise temperature intercepted by ground Deep-Space antennas has been developed, based on simulations obtained by using a radiative transfer model approaching the electromagnetic propagation in a scattering medium. A model dependent on attenuation, frequency and elevation angle is proposed for describing the atmospheric mean radiative temperature, which relates sky-noise temperature to attenuation. Model validity ranges from X to lower W band for space research allocated bands and for elevations between 10 deg and 90 degrees.File in questo prodotto:
