Abstract
A numerical scheme for calculating direct and inverse double-weighted Fourier transform (DWFT) in the problems of wave propagation in inhomogeneous media on the basis of the fast Fouriertransform algorithm is proposed. The sampling step for which it is possible to recover a continuous field without information loss is estimated. The numerical calculation data are given and the obtained results are discussed.
