A two-dimensional density is constructed from given marginals and a given correlation coefficient by using an expansion in orthogonal polynomials. The results are used to derive a general method of finding the field scattered by a rough surface by both physical and geometrical optics when the surface is generated by a stationary random process which is not necessarily normal. The example of an exponential surface is calculated in more detail, particularly for backscatter.
