The Application of 3D Rain Scatter Model on Horizontally Polarized SHF Signal Propagation in Tropical Location

This paper presents some results of intersystem interference as a result of hydrometeor scattering on horizontally polarized SHF signal propagation in the tropical environment using the 3D rain cell model. The cumulative distribution of transmission loss has been based on the distance dependence (terrestrial station to the center of the common volume distance); frequency dependence and antenna gain dependence. Though there is a less interference (significantly higher transmission loss) at a relatively higher frequency of 20 and 34.8 GHz, the rain-scatter interference problem may not be negligible for a tropical region with high rainfall rate because, for a small percentage of time, the rain scatter power can be received even at a large distance from an interfering station.
