Samenvatting

Techniques are presented for the digital simulation of the height profiles of a number of correlated parallel tracks and of an entire two-dimensional random road surface. It is shown that the profiles of a number of correlated tracks may be generated by using the one- dimensional discrete Fourier transform, but, in order to generate a fully isotropic surface, it is necessary to use two-dimensional Fourier transform methods and these are discussed in detail.
