The computation results of WA-3DPE are more closer to measurement results than those of WA-2PDE, as the WA-3DPE considers the horizontal diffraction propagation.
Combination of the Improved Diffraction Nonlocal Boundary Condition and Three-Dimensional Wide-Angle Parabolic Equation Decomposition Model for Predicting Radio Wave Propagation
where [d.sub.min] [less than or equal to] d < [d.sub.LS] is the visual distance spread, [d.sub.LS] [less than or equal to] d < [d.sub.x] is the diffraction propagation distance, and d [greater than or equal to] [d.sub.x] is the scattering propagation distance.
Parameter Estimation for the Field Strength of Radio Environment Maps
Therefore, we usually use either the free-space, two-ray, or knife-edge diffraction propagation models in EW applications.
