Abstract :
Measurements on the copolar level of the 11.575 GHz OTS-Earth link have been analysed during the year 1981, using a 1 s sampling time. The variation of the fluctuations amplitude is evaluated as a function of the time of day and of the month of the year. It is compared to the number of attenuation events over the same period and against the same parameters. The statistic of the number of occurrences is calculated as a function of the amplitude of the events.
