In this paper, the z-transform of two-dimensional discrete random pattern autocorrelation model is derived. A linear model of z-transform coefficient is established and the model is identified. Logarithmic identification method is proposed for two-dimensional separable index model. The results of the terrain model and image pattern recognition confirm the correctness of the method and the accuracy of the results.
