Abstract：This paper proposed a new clutter reduction method based on characteristic of Ground Penetrating Radar(GPR) image in detecting shallow subsurface objects. Moreover, a method to realize fast synthetic aperture imaging based on the proposed clutter reduction method is proposed. The results of processing measurement data show the proposed clutter reduction method is very effective and universally valid; The resolving power of image gained by the proposed fast synthetic aperture imaging method corresponds with that general synthetic aperture imaging method, thanks to the proposed method can eliminate the influence of clutter, so the processing speed is improve greatly comparing with general synthetic aperture imaging method, the effect of image gained by the proposed method better than general synthetic aperture imaging method.
