f 3DGPR FOR DISASTER MITIGATION AND ARCHAEOLOGICAL SURVEY IN JAPAN

After the East Japan Great Earthquake and Tsunami, we are planning to move houses to higher please. In this case, we have to carry out archaeological survey before the development, and we expect great amount of demand will be created. We think the high accuracy GPR measurement methodology (3DGPR) which we are developing will have very high potential for this solution. 3DGPR is capable for survey on uneven ground surface, which was very difficult by conventional GPR. We have developed #DGPR system with University of Miami, and applied in many targets. In this report, we will summarize some archeological surveys we have conducted, and discuss on the limitation of GPR in practical situations.
