Essentially, all models are wrong, but some are useful - George E.P. Box
Researchers in the signal processing community often require sensor signals that result from a spherically or cylindrically isotropic noise field for simulation purposes. Although it has been shown that these signals can be generated using a number of uncorrelated noise sources that are uniformly spaced on a sphere or cylinder, this method is seldom used in practice. In this paper we develop algorithms that generate sensor signals of an arbitrary one- and three-dimensional array that result from a spherically or cylindrically isotropic noise field. Furthermore, the influence of the number of noise sources on the accuracy of the generated sensor signals is investigated.
