Characterization and modeling of the influence of the intensity of precipitation on Ka-band satellite communication systems
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
To compensate the strong Troposheric impairments caused in the Ka frequency band, it is necessary to use Fade Mitigation Techniques. To develop and validate such techniques, time series of rain attenuation are needed. Nevertheless, these data are difficult to obtain. An alternative to using real rain attenuation time series is to develop a model of rain rate time series synthesizer. Nevertheless, real rain rate time series are needed to develop and validate this model. The aim of this internship is to provide real rain rate data useful for the development, parameterization and validation of this new model. In the first part of this report, different rain rate computation methods will be presented. Then, real data from a rain gauge located at Onera premises in Toulouse will be processed according to the presented methods and to a novel one. Results will be statistically analysed and finally a study of both the error of the methods and the uncertainty of the experimental devices and tools will be carried out.
