Abstract :
An improved method of diffraction loss calculation based on the Fresnel-Kirchoff scalar theory is presented. According to this method a more exact modelling of natural and man made obstacles is introduced by considering longitudinal and lateral profiles as well. An error analysis is performed to determine the necessary accuracy and the minimum lateral extent of the model to be considered for the calculations. Numerical results are presented to show the improvement achieved in the accuracy of diffraction loss calculations
