Abstract

In wave-based remote sensing of distant objects embedded in a random medium a high-frequency electromagnetic wave is scattered by object discontinuities, and portions of the scattered radiation can traverse the same random inhomogeneities as the initial incident field, leading to an anomalous intensity distribution. Here, we present a possible realization for the resolving properties of an object using the double-passage effects and construct the intensity response at the image plane of an optical system, resulting from backward reflection from a target having discontinuities. The object plane-image plane relations are formulated and manageable algorithms are obtained by using the random propagators of the Stochastic Geometrical Theory of Diffraction. The resolving properties of periodic spatial objects ar investigated.
