Relationship between Source Height and Distance Order of Propagation Along Random Rough Surface
This paper is concerned with a relationship between source height and the field attenuation along random rough surfaces (RRSs). First we introduce a discrete ray tracing method (DRTM) to numerically compute field distribution along RRSs. Second we review Hata's equation which is an empirical formula obtained by many out door data, and discuss that the field distribution in urban area depends on the antenna height. Finally we show the field distribution along RRSs computed by using the DRTM. We confirm whether the field distributions above RRSs depends on the source height or not.
