The measurement of the intensity of a wave propagating in a random medium results in a random signal response, the statistical properties of which are functions of the radiation wavelength and the ratio between the characteristic scale of the spatial intensity pattern and the size of the receiver aperture. In this paper, using multiscale solutions for high-frequency random propagators, we construct expressions for the integral intensity correlation measures that allow us to obtain the spectral intensity correlation characteristics and to analyze their variations as functions of wavelength separation and detector aperture. Numerical results are presented for a plane wave propagating in random media that are characterized by a Gaussian spectrum and by a power-law spectrum of the refractive-index fluctuations.
