Abstract
The radiowave propagation is a very important research content in the research of engineering and theory. The Fourier stepping algorithm for the parabolic equation is an effective method, which can create a balance between the accuracy and the speed of the calculation. In the analysis and research of this paper, the calculation results considering the Fresnel diffraction have been compared with the calculation results of the parabolic equation. In the numerical calculation study, the influence of the parabolic equation maximum deviation angle, the Fourier transform data points and the discrete interval to the results of the obstacle diffraction has been discussed.
