查询词典 scintillations

In this paper, effects of atmospheric factors to Ka-Band earth-space links are analyzed, and the total fade distribution function is derived. With the scintillation prediction model, monthly averaged standard deviations and monthly percentage time averaged fade of scintillations for some of referential earth stations of our country are computed.
