Ultra-wideband outdoor channel modeling using ray tracing techniques

An ultra-wideband (UWB) channel modeling approach using ray tracing techniques is presented. The scenario consists of a farm area with clusters of scatterers over moderately varying terrain. The channel sounding consists of power-scaled distinct frequencies whereby all relevant ray signal descriptors are captured. From this we develop a two-ray and three-ray path loss model with associated parameters. The technique is suitable for UWB channel characterisation using narrowband channel sounding in outdoor environments with small number of scatterers over moderately varying terrain.
