Improvement of the ONERA-CNES rain attenuation time series synthesizer and validation of the dynamic characteristics of the generated Fade events

To develop and test real-time Fade Mitigation Techniques control algorithms, propagation time series are needed. An alternative to using real data collected from propagation experiments is to generate typical fading time-series making use of climatological characteristics as well as geometrical and radio-electrical parameters of the link. The objective of this paper is to present the improvement of the rain attenuation dynamic model based on the Maseng-Bakken model. Some of the theoretical hypotheses have been verified, a methodology to assess input parameters has been tested, and the sensitivity of the model with respect to internal parameters has been studied. Then, a new validation methodology that aims at assessing the physical soundness of synthesized events has been developed. Finally it has been applied to the ONERA-CNES channel model.
