The backscattering from a random medium is analytically studied. The result gives a mathematical foundation to the cumulative forward-scatter single-backscatter (CFSB) approximation proposed by de Wolf. The multiple scattering effects on backscattering of a plane wave incidence are examined for both Fresnel and Fraunhofer scatterings with various correlation functions of turbulence. As a result, it is found that the multiple scattering effect on the backscattering is sensitive to the statistical properties of the fluctuating medium.
