Tropospheric Scintillation of Ku and Ka-Band Satellite Signals in South Indian Region

Abstract

Tropospheric scintillation can be categorized under one of the transmission impairment. Admitting the affects is only a short time fluctuating signal, but it can give severe signal degradation on satellite-earth link that operates at 10 GHz and above. Most of the scintillation prediction model was implemented based on four season countries climate. Tropical climate was known as uniform temperature, high humidity and heavy rain characteristics in which so different with four seasons climate. Scintillation will occurred no matter the in clear sky condition or raining. So, this proposed paper work aimed to evaluate the performance of tropospheric amplitude scintillation in tropical region at clear sky condition. To estimate the statistic ]of tropospheric scintillation in Indian region based on the parameters in ITU-R model. To observe the relationship between the scintillation intensity and the local environmental parameters. An experimental satellite signal measurements need to analyse, and their statistical behaviour of the propagation effects to be compare with the theoretical background. And their link parameters to be compare with meteorological parameters. New prediction models for the propagation effects could be develop and need to specify the improvements to existing models.
