Fluctuations on OTS-earth copolar link against diurnal and seasonal variations
Abstract
Measurements on the copolar level of the 11.575 GHz OTS-earth link are analyzed for the year 1981 using a 1 s sampling time. The variation in the fluctuation amplitude is evaluated as a function of the time of day and the month of the year. It is then compared with the number of attenuation events over the same period and against the same parameters. A calculation is made of the statistics of the number of occurrences as a function of the amplitude of the events. The statistics of the number of peaks of fluctuation are found to show a definite relationship with the fluctuation amplitude.
