Wide Area Archaeological Site Investigation using Ground Penetrating Radar

利用探地雷达（GPR）对古代政府建筑、聚落和寺庙遗址进行了广泛的地下考古现场调查。这项研究的目的是确定探地雷达的适用性，以准确地从具有不同地面条件的各种遗址中探测地下考古，并测试将这项技术应用于广域遗址的可行性。作为初步调查的一部分，成功实施了通过雷达数据后处理获得更深穿透深度的方法。研究的示例地点包括iki - harunnotsuji地点。这个地点非常有趣，因为目标包括一个古老的河道和船只登陆区，埋得很深，上面覆盖着由湿粘土组成的上层土壤。这些场地条件被认为极难使探地雷达发挥作用。在研究计划的早期阶段，一次试验测量能够探测到目标通道和着陆区域，并通过电磁测量（EM）证实了探地雷达的结果。在不同的地面条件（如土壤湿度条件）下，进行了多次探地雷达和电磁测量。研究发现，考虑到场地的天气和自然环境，当土壤条件最理想时，可以获得成功的调查结果。然而，当地面条件不理想时，目标特征是无法检测到的。其他调查地点包括寺崎寺遗址（宫崎县斋藤市）、日高遗址（群马县高崎市）的古代政府场地和下田寺遗址（兵库县姬路市）。在吉野村遗址（佐贺金崎町）也对陶器罐葬进行了调查，调查结果表明，探地雷达不仅能够探测到这些埋葬，而且数据表明，这些埋葬也可以分为幸存的完整埋葬罐和倒塌的埋葬罐。这些研究的总体结论是，探地雷达可以成功地应用于广域考古遗址调查研究。少

Wide area site investigation of subsurface archaeology of ancient government buildings, settlement and temple grounds were remotely studied using ground penetrating radar (GPR). The objective of the study was to ascertain the applicability of GPR to accurately detect subsurface archaeology from a variety of sites having different ground conditions and to test the feasibility of applying this technology over wide area sites.As part of the preliminary investigation, methods to obtain deeper penetration depths were successfully implemented from post-processing of the radar data On example site studied included the Iki-Harunotsuji site. This site was very interesting in that the targets which included an ancient channel and boat landing area, were buried very deep and were also overlain by upper layer soils which consisted of wet clay. These site conditions were considered to be extremely difficult for GPR to be effective. In the early stage of the research program, a trial survey was able … More to detect the targeted channel and the landing area The results from GPR were also confirmed by an electromagnetic method (EM survey. The GPR and EM surveys were conducted several times in which the site had different ground conditions (e.g. soil moisture conditions). It was found that successful survey results could be obtained when ideal soil conditions were most favorable considering the weather and natural environment of the site. The target features however were undetectable when the ground conditions were not ideal.Other survey sites include the Terasaki temple site (Saito-shi, Miyazaki), the ancient government grounds at the Hidaka Site (Takasaki, Gunma), and the temple site at Shimooda (Himeji, Hyogo). Earthenware pot burials were also investigated at the Yoshinogari site (Kanazaki-cho, Saga) where survey results indicate that GPR was not only able to detect these burials, but the data suggest that these burial can also be classified between surviving intact burial pots and collapsed burial pots. The general conclusion of these studies were that GPR can be successfully applied to the study of wide area archaeological site investigations. Less
