In this paper, Split-Step Wavelet Method (SSWM) is proposed to model radio wave propagation in horizontally inhomogeneous environment. The performance of SSWM is investigated for laterally heterogeneous environment condition. Further, Split-Step Fourier transform Method (SSFM) is implemented on the same platform to model radio wave propagation under similar environmental conditions. Finally, results...
In this work, a novel Split-Step Wavelet Method (SSWM) is developed for the solution of two dimensional parabolic equation to model the radiowave propagation in tropospheric ducts. Galerkin projection method with periodic Daubechies wavelet is used to discretize the symmetrically extended height operator. Later, a marching algorithm like Split-Step Fourier transform Method (SSFM) is developed by taking...
In this work, a finite element method (FEM) based solution of parabolic wave equation (PWE) is presented to model the radiowave propagation in evaporation duct. One dimensional piece-wise linear polynomial functions are used to discretize the height operator. By applying this discretization process, PWE reduces to an ordinary differential equation (ODE). Later, ODE is solved by Crank-Nicolson method...
