Near-Earth Wave Propagation Modeling

Researchers: Dahan Liao and Kamal Sarabandi

We are in the process of assembling high fidelity, physics-based propagation models that will enable accurate prediction of radiowave interactions with a realistic terrain over long distances with the inclusion of ground proximity effects. Wave propagation issues pertinent to the modeling of different terrain features such as small and large scale random undulations, continuous and truncated dielectric coverings in the form of foliage and snow layers are being analyzed. The emphasis of the study is on applications related to channel performance characterization and macro/micro grid planning of unattended ground sensor (UGS) networks deployed in a natural environment.
