Abstract

We confront the problem of retrieving statistical parameters from statistical functions characterizing random or pseudorandom surfaces. Some complications arise when the definition of the autocovariance length for a pseudorandom surface is considered. These complications are carefully investigated, and solutions are proposed to overcome them. In particular, a deduction of certain statistical parameters from the spectrum instead of the autocovariance function is proposed.
