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

Abstract

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.
