Decrypting XPD-CPA beacon measurements through a physical simulator

Complex physical models are necessary to interpret the patterns of microwave attenuation versus depolarization gathered from measurements along Earth-to-satellite paths, due to the layered structure of the atmosphere in the presence of precipitation or clouds. Here we show that a simulation tool previously developed and based on physical concepts achieves good results when checked against measured patterns in a few case studies. Upon further validation, the simulator could be useful in assessing the effects of interference in the design of satellite systems based on polarization diversity.
