我们提出了一种新的探地雷达（GPR）方法探测埋地地雷。使用天线阵列的探地雷达系统用于共中点（CMP）数据采集。该系统使用10个Vivaldi天线的所有阵列，工作频率为30 MHz至6 GHz。对共中心点资料进行时差校正，并进行叠加压制地杂波。该系统在实验室中进行了测试，我们表明它以高分辨率对埋在地下的地雷状目标进行成像。将一个72型塑料地雷模型埋在由砾石和碎石混合物组成的土壤中，并可以通过所提出的技术进行检测。CMP处理应用于阵列信号有效地抑制了来自粗糙地表和非均匀土壤的杂波。结果表明，该方法对地杂波的抑制是有效的，但如果与CMP技术相结合，效果会更好。
We propose a new ground-penetrating radar (GPR) methodology for buried land-mine detection. A GPR system using an antenna array was used for common-midpoint (CMP) data acquisition. This system uses all array of ten Vivaldi antennae and operates from 30 MHz to 6 GHz. The moveout of the CMP data was corrected and the data were stacked to suppress ground clutter. The system was tested in the laboratory and we showed that it images buried mine-like targets with a high resolution. A model of a plastic land-mine of Type-72 was buried in soil consisting of a mixture of gravel and crushed rocks and could be detected by the proposed technique. CMP processing applied to the array signal effectively suppresses the clutter from rough ground surfaces and inhomogeneous soil. We found that the migration algorithm is effective in suppressing ground clutter, but it is even more effective if it is combined with the CMP technique.
