Abstract

We show that the cross-spectral density in the far zone of a homogeneous spherical source can be described as a low-pass 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 ξ has a functional structure of the form 1ξ2, for 0ξ1. The cases of spatially incoherent and Lambertian sources are treated as significant examples.
