Abstract Based on range migration imaging technique, this paper investigates ground penetrating radar three dimension imaging algorithm under near field condition, discusses the back propagation algorithm at the same time. Theoretical analysis shows that near field 3-D range migration imaging technique can reduce computational complexity in much degree by contrast with back propagation algorithm. Finally, through processing the experimental data, 3-D images of underground objects are obtained. The results validate the correctness of the near field 3-D range migration imaging algorithm and its capability at the aspect of real time processing.
