Abstract

"We show that the cross-spectral density in the far zone of a homogeneous spherical source can be described as a lowpass. filtered version of that existing across the source surface. We prove that, to an excellent approximation, the. corresponding filter with respect to a (normalized) spatial frequency $\\xi$ has a functional structure of the form $\\sqrt{1-\\xi^2},. for $0 \\le \\xi \\le 1$. The cases of spatially incoherent and Lambertian sources are treated as significant examples."
