Abstract: The construction of difference schemes, describing the results of observations of 2D spatio-temporal functional dependencies and a numerical method for definition the parameters of such dependencies on the basis of difference schemes are considered. The algorithm of method including iteration procedure for mean-square estimation of coefficients of linear parametric discrete model in the form of stochastic difference equations. Such an approach to solving the problem of identification of 2D dynamic processes can ensure a high adequacy of a model, and as a consequence, to achieve high accuracy of estimating the parameters of the model.

Keywords: parametrical identification, difference scheme, root-mean-square approximation.
