review text: In this paper, the framework for the analysis of cross correlations of noise signals is presented. Imaging by cross correlation of noise signals is reviewed briefly for a homogeneous background. The main result of the paper addresses cross correlation based passive array imaging in a weakly scattering medium. Also, a case is considered in which scattering is not generated by random inhomogeneities but by a deterministic reflecting interface in medium. The authors show how the use of iterated (fourth-order) cross correlations and appropriate imaging functionals can improve the resolution and the signal-to-noise ratio of passive sensor imaging in a scattering medium. Numerical simulations to illustrate the results of the paper are carried out.
