| | Abstract | | Multi-channel ground-penetrating radar (GPR) becomes utilized for many subsurface targets recently. However, many successful survey targets can also be detected by single channel GPR in old years. We believe the multi-channel GPR has higher potential to investigate more sensitive targets, which cannot be detected using any geophysical exploration techniques. We consider that one of key technologies to solve the problems is measuring survey positions with high accuracy. Thus, we try to improve the accuracy of positioning for the multi-channel GPR to adjust relative survey locations of multi-channel records. |
