Rain fade dependence model of long-term scintillation amplitude distribution at 12.5GHz

An extension of current scintillation stochastic models is described to exa mine the alteration of the scintillation amplitude distribution with the co ncurrent rain fade depth on earth-space paths. Descriptive statistical resu lts of 12.5GHz scintillation at two sites show that the long-term magnitude of tropospheric scintillation steadily increases with worsening rain atten uation.
