摘要

This paper presents a cosine-based back-projection(CBP) algorithm for ground penetrating radar(GPR) imaging to detect underground holes. Compared with the classic back-projection imaging algorithm, the CBP algorithm provides a better performance due to better effect of clutter suppression. In the proposed algorithm, a cosine-based measure function is established to describe the similar feature between every two different echo signals to achieve excellent artifact suppression. Then numerical simulation and experimental data set were used to test the SBP algorithm. The experimental data set was gained in Double Han Road, Siming District of Xiamen, China, and acquired by the the Latvia radar system, zond-12e model, which has a 115 kHz transmitting frequency, 40/80/160/320 Hz scanning frequency, ±40dB receive gain and 2000ns time-window width. The results fully demonstrate the effectiveness and superiority of CBP algorithm.
