This paper proposes a space-time statistical geometric model for characterization of multipath propagation of the satellite communication, which provides some insight into the spatial properties of wideband channels. The Closed-form explicit expressions of the probability density functions (pdf) of the Time Of Arrival (TOA) for multipath signals and the power delay profile according to the various elevation angles of the satellite are derived, where the scatterers are located uniformly within a Three-Dimensional (3-D) hemisphere around the receiver.
