摘要

利用超宽带探地雷达模拟和基尔霍夫偏移法解决了地下目标深度的确定问题。电磁问题采用时域有限差分法计算。电磁场源为纳秒级的平面电磁波，垂直入射于地平面。通过测量地空界面以上一定高度处的反射电磁场，获得a扫描图。以b扫描形式产生的散射场通过Kirchhoff迁移法进行处理，以确定隐藏物体的确切深度。

Kirchhoff Migration Method for Tube Detection with UWB GPR

The problem of subsurface object depth determination is solved by the ultrawideband ground penetrating radar simulation and Kirchhoff migration method. The electromagnetic problem is calculated by the FDTD method. The source of electromagnetic field is a plane electromagnetic wave of nanosecond time duration with normal incidence to the ground plane. A-scans are obtained by measuring the reflected electromagnetic field at the certain height above the air-ground interface. The resulting scattered fields in the form of B-scans are processed by Kirchhoff migration method in order to determine the exact depth of the hidden object.
