摘要

我们发现，使用hycell模拟雨场对地球- leo ka波段链路进行的模拟:(1)产生的衰减斜率略低于基于excellle的模拟雨场;(2)对选定的地球- geo ka波段链路的实测数据拟合略好。然而，差异非常小，EXCELL模型产生的稍微保守的估计在很大程度上被它的更简单性所抵消。

Effect of rain cell shape on fade slope statistics over simulated Earth-LEO Ka-band links

We show that simulations of Earth-LEO Ka-band links conducted using HYCELL-based simulated rain fields: (1) yield slightly lower fade slopes than do EXCELL-based simulated rain fields and (2) fit measured data on selected Earth-GEO Ka-band links slightly better. However, the differences are very small and the slightly conservative estimates yielded by the EXCELL model are offset to a large extent by its greater simplicity.
