| 摘 要： | 该文基于探地雷达(Ground Penetrating Radar, GPR)回波数据之间的互相关性，提出了一种用于抑制GPR成像中杂波干扰的反向投影(Back Projection, BP)成像算法。与标准BP算法相比，该文的互相关反向投影(Cross-correlated Back Projection, CBP)算法增加了数据间互相关运算的步骤，而且无需引入额外的参考信号通道。理论分析和实验结果均表明，CBP算法不仅抑制了标准BP算法成像结果中的杂波干扰，而且在一定程度上提高了成像分辨率。

| Abstract: | 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 ... |
