Abstract

Enhancing the accuracy of atmospheric loss modeling holds the potential to significantly refine estimations of received power, thereby enhancing the overall quality of satellite communication links. This study aims to pioneer and validate an innovative modeling framework to reliably predict atmospheric attenuation along satellite-to-ground propagation paths, particularly focusing on portions of the W-band (81-86 GHz) and V-band (71-76 GHz). By leveraging meteorological data, this approach will encompass various weather scenarios, including clear skies, cloud cover, and diverse forms of precipitation. Utilizing the generated time domain data, the research aims to construct complementary cumulative distribution functions, enabling the analysis of satellite links with heightened precision and reliability. The hypothesis of this research is that such a model can provide reasonable statistics for an annual period, despite (1) radiosonde data only being available twice per day, (2) the uncertainty of cloud formation, and (3) the limitation of only having point measurements of precipitation events (as opposed to distributed measurements along the propagation path). This model is validated using radiometer and beacon measurements obtained in collaboration with the Air Force Research Laboratory, Space Vehicles Directorate.
