Backscattering response from periodic spatial patterns in random media

In wave-based remote sensing or radio-location of distant objects in a rand om medium, a high-frequency electromagnetic wave is scattered by object dis continuities, and portions of the scattered radiation can traverse the same random inhomogeneities as the initial incident field. The statistical depe ndence of the forward-backward travelling events results in an anomaly in t he backscattered intensity pattern that carries information about the scatt ering object. The quality of this information depends on the ability to res olve the fine-structure elements. In this work we investigate the resolving properties of periodic spatial objects by using the random propagators of the stochastic geometrical theory of diffraction.
