Abstract

We consider the problem of detection of a conducting target on a random rough surface and introduce a new method based on exploiting angular correlation function (ACF) of the backscattered signal to improve detection performance. We show that ACF exhibits better signal to clutter ratio than that of backscatter RCS. We analyze the probability distribution function of the expected returned signal and the correlation function to generate the respective ROC curves and compare performance.
