HiRadProp: High-Frequency Modeling and Prediction of Tropospheric Radiopropagation Parameters from Ground-Based-Multi-Channel Radiometric Measurements between Ka and W Band
Abstract
Sun-tracking microwave radiometry is a ground-based technique where the Sun is used as a beacon source. The atmospheric antenna noise temperature is measured by alternately pointing toward-the-Sun and off-the-Sun according to a beam switching strategy. By properly developing an adhoc processing algorithm, we can estimate the atmospheric path attenuation in all-weather conditions. A theoretical framework is proposed to describe the Sun-tracking radiometric measurements and to evaluate the overall error budget. Two different techniques, based respectively on elevation-scanning Langley method and on surface meteorological data method, are proposed and compared to estimate the clear-air reference. Application to available Sun-tracking radiometric measurements at Ka, V and W band in Rome (NY, USA) is shown and discussed together with the test of new physically-based prediction models for all-weather path attenuation estimation at Ka, V and W band from multichannel microwave radiometric data. Results show an appealing potential of this overall approach in order to overcome the difficulties to perform satellite-to-Earth radio propagation experiments in the unexplored millimeter-wave and submillimeter-wave frequency region.
