We consider anisotropic self-similar random fields, in particular, thefractional Brownian sheet. This Gaussian field is an extension of fractionalBrownian motion. We prove some properties of covariance function forself-similar fields with rectangular increments. Using Lamperti transformationwe obtain properties of covariance function for the corresponding stationaryfields. We present an example of a Gaussian self-similar field with stationaryrectangular increments that is not a fractional Brownian sheet.
