METHOD AND APPARATUS FOR THROUGH-THE-WALL MOTION DETECTION UTILIZING CW RADAR

摘要

A CW radar (10) is used to detect motion of objects (22) behind a wall (20) by projecting a radar beam through the wall and by measuring the returns from the objects behind the wall, with a change in the phase difference between the transmitted and received CW signals providing an indication of motion behind the wall and thus the presence of an individual.
