A method is presented that allows closed-form expressions for the correlation function to be obtained for arbitrary scattering distribution functions. These closed-form expressions are derived for a variety of commonly used scattering distribution functions.Keywords: Correlation methods; Natural frequencies; Scattering; Sensors; Wave propagation; Scattering distribution functions; Signal theory Scattering distribution; Sensors; Spatial correlation200210.1109/LSP.2002.8041382015-12-11
