Space Weather Effects on RF Propagation

Authors: Antonio M. Casimiro; UNIVERSITY OF ALGARVE FARO (PORTUGAL)
Abstract:
This report results from a contract tasking University of Algarve as follows: The Grantee will 1) apply Maxwell's equations with vector radiation processing to determine how virtual antennas can be developed using the Huygens principle; 2) study the propagation medium to determine which physical parameters are important for radiation parameters of the spatial distributions of radiating sources and to establish the relationships among them. The aspects of the propagation medium that are to be studied depends on the GPS propagation error estimation and correction, after optimization of the model parameters; 3) simulate point to point links using the new procedures developed as a result of tasks 1 and 2 above; and 4) use classical point to point propagation links models to verify the newly developed propagation models of the virtual antennas procedure to provide a reference for, and to quantify the accuracy of, the newly developed models.
