Abstract :
Fourier transform methods in a three-dimensional parabolic equation are presented in this paper. Decomposing the double integral to three one-dimensional Fourier transforms, three-dimensional parabolic equation can be computed by means of fast-Fourier transforms. Comparing the results with the two-ray model, the validity of the methods is testified.
