In this paper, suppose the terrain is an ergodic wide-sense stationary two-dimensional random field with zero mean value on a local region, the basic property of its two-dimensional autocorrelation function is investigated.
本文假定在局部区域上,地形是一个零均值各态历经的宽平稳二维随机域,研究了其二维自相关函数的基本性质。
in this paper the z transform of the autocorrelation model for two-dimensional discrete random pattern is derived, and the linear model for the coefficient of z transform is established and identified.
