Radio Propagation Prediction Software for Complex Mixed Path Physical Channels

"Modern and future wireless communication and information warfare systems composed of structured and ad hoc networks are required to function in extremely diverse environments across a wide range of frequency bands. These systems face challenges ofoperating within dense urban settings, rural or desert conditions, across rapidly varying terrain, within and amongst buildings, through foliage, and combinations of the above environments. Maintaining effective communication links and information warfareoperations in such diverse geometrical and electrical conditions presents a serious challenge to the warfighter, network planner, and system designer.The objective of this proposal is to demonstrate the feasibility of creating a single propagation prediction tool of revolutionary capabilities that can accurately analyze RF propagation scenarios of arbitrary complexity with rapid turnaround. This toolwill be able to characterize RF propagation over a wide frequency band (50MHz - 100GHz) and through diverse environments including urban, rural, foliage, and building interiors. The propagation model will be fully three dimensional with regards to thehigh fidelity scene models representing various geometric structures and the physics employed. The physics-based model developed will incorporate high- and low-frequency effects such as rough-surface diffusive scattering and ground waves, as well as anaccuracy `tuning' capability. The resulting
