WebDec 31, 1991 · In this paper an analytical equation of the sound level distribution caused by a rectangular noise source is derived. It is assumed that the area elements of the noise source radiate the... WebOct 24, 2012 · Note, the PSF for an incoherent system is different than the PSF for a coherent system- again, Goodman's book covers this amazingly well. As per your example, the sun is a fairly spectrally incoherent source, and unless the grating has some phase information, since your eye can only respond to intensity, this is incoherent imaging.

Incoherent … WebApr 1, 2024 · The POD method is used to decompose the sound field in the frequency domain. It helps to establish the relationship between coherent structures of sound field and locally coherent noise sources. In addition, the method can also be used to eliminate the influence of background noise by selecting POD modes with higher energy.
