Abstract
On the basis of graphical ray tracing along with the link geometry and
configuration, this paper develops a simplified graphical - numerical technique
to estimate the multipathing parameters associated with the multiple paths
resulting from a given vertical refractivity profile of a two-layer troposphere.
The proposed model is verified by applying it to analyze the performance of
different microwave line of sight (MLOS) links with different parameters and
configurations. The multiple-path rays are displayed over each MLOS link with
a given geometry and configuration. The numerical results are discussed and
compared with the corresponding published data using different techniques. The
results show clearly the dependence of multipath parameters on refractive index
gradient, link geometry and link configuration.
