Abstract
An efficient technique based on the fast Fourier transform (FFT) and linear interpolation is presented for the evaluation of the scattering by a rough terrain profile with very large correlation length. If introduced in a BMIA/CAG method, it can reduce the computation time significantly. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 280–282, 1999.
