An Improved Iteration Back Projection Imaging Technique for Surface Penetrating Radar Applications

Abstract:

Traditional back projection(BP) imaging algorithm can be used to obtain 2-dimensional subsurface imaging results of testing materials and thus provide useful information for material nondestructive testing(NDT). But it’s restricted by heavy computation burden and cannot be widely used in surface penetrating radar(SPR) NDT area. To meet the needs of high resolution imaging and low computation burden, an improved iteration back projection imaging algorithm is presented. With the multi scale iteration processing and local maximum extraction method, it can get appropriate resolution imaging results with much lower computation. The simulation of this algorithm is processed and experimental results validate the feasibility of this algorithm.
