Bispectrum for non-Gaussian homogenous and isotropic field on the plane

Abstract

The object of this paper is to characterize the third order moments (cumulants) and bispectra of a homogeneous isotropic field defined on a plane. We establish a one to one correspondence between the third order cumulants and the bispectra of such a process in terms of Bessel functions.
