摘要

In the literature it is shown that the prediction of path loss over hilly terrains for a knife edge obstacles always gives value which is different from the actual one due to its difference from actual shape. Therefore in this paper path loss is obtained for a hilly terrain which is cylindrical (rounded in 2D) in shape from the top using Fresnel-Kirchhoff knife edge theory of diffraction with cylindrical correction factor. The results obtained for the cylindrical shape are compared this with the Fresnel-Kirchhoff knife edge diffraction theory as well as the measurement data available for such scenarios in the literature. The results shows that there is no significant variation in the path loss obtained for cylindrical obstacle over approximated knife edge obstacle but it increases computational complexity as compared to knife edge approach.
