A method for improving near-field BP imaging that Uses radiation pattern compensation

Abstract

This paper presents a method for acquiring the spatial structure of a target using millimeter-wave radar under near-field conditions and imaging a 3D target using 2D and 3D BP imaging methods. The situation that bright spots appear in the BP imaging algorithm to affect the imaging effect is analyzed. A compensation method using the radiation pattern is proposed to achieve the suppression of bright spots caused by strong scattering points. The 2D and 3D BP imaging effects are improved. The correctness of the method is verified by comparing the measured data.
