A high resolution medium penetrating imaging radar system

High resolution medium penetrating imaging radar is a kind of important equipment which can be widely used in military, security, construction and other fields. For the sake of imaging the target buried in the medium fast and in high resolution, this paper analyzes the theory of high resolution medium penetrating imaging, proposes two dimensional fast scan method which combine column staggered array antenna with lead rail, presents the process of near field synthetic aperture imaging and structure of the prototype. In the end, the result of imaging test of the prototype is given. The prototype can penetrate 2.5cm board and image the small target, the imaging resolution is better than 1cm.
