Abstract
Aiming at the problem of side obstacles on the transmission path, an algorithm for more accurate prediction of field strength has been proposed. The algorithm uses the slant profile which is determined by the antenna line and the minimum Fresnel radius to gather the information of the side obstacles, determine the Fresnel clearance and calculate the diffraction loss. The simulation results show that the side obstacles can produce the diffraction loss in the radio wave propagation as same as the vertical obstacle can, and verify the correctness and rationality of the attenuation calculated by the method in the case of the side obstacle.
