Detection of a target in a homogeneous medium using angular correlation function

A novel technique for detecting a target buried under a homogeneous medium is presented. This technique is based on a phenomenon known as the angular memory effect, and involves measurement of the angular correlation function (ACF) for scattered waves observed at antenna positions where the masking effect of the medium on the desirable target ACF return is minimized. Millimeter-wave experiments were conducted to demonstrate the effectiveness of this technique
