title = "Detection of intensity fluctuations in a random medium with a finite aperture detector",
abstract = "A high-frequency electromagnetic wave propagating through a randomly inhomogeneous medium will create random intensity pattern whose spatial structure is a function of the radiation wavelength and the parameters of the medium. The ability to detect the spatial variation and to find correlation between different patterns depends on the ratio between the receiver aperture and the characteristic spatial scale of the speckle. In this work, using the multiscale expansion solutions for the nonaveraged coherence functions, we have constructed expressions for the integral correlation characteristics and performed a qualitative analysis of the correlation dependences as functions of range and detector aperture for media with Gaussian and power-law refractive index fluctuation spectra. Numerical computations are presented and comparison with the asymptotic results obtained for the strong scattering regime is performed.",
