A Ground Penetrating Radar Back Projection Imaging Algorithm Based on Cross-correlation

Based on the cross-correlation of the received data of Ground Penetrating Radar (GPR), a novel Back Projection (BP) algorithm is proposed to suppress the artifacts in the results of GPR imaging. Comparing with standard BP algorithm, the proposed Cross-correlated Back Projection (CBP) algorithm adds the procedure of calculating the cross-correlation of the received data without increasing any additional channel for reference signal. Both the theoretical analysis and the experimental results present the superiority of the CBP algorithm over standard BP algorithm in artifacts suppression, as well as a slightly improvement in image resolution.
