Wide Area Archaeological Site Investigation using Ground Penetrating Radar

利用探地雷达(GPR)对古代政府建筑、聚落和寺庙遗址的地下考古进行了大面积的现场调查。该研究的目的是确定探地雷达在各种不同地面条件的遗址中准确探测地下考古的适用性，并测试这项技术在广域遗址应用的可行性。作为初步调查的一部分，通过对所研究的Iki-Harunotsuji遗址的雷达数据进行后处理，成功地实施了获得更深穿透深度的方法。这个遗址非常有趣，因为目标包括一个古老的航道和船只登陆区，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是探地雷达发挥作用的极大困难。在研究计划的早期阶段，一项试验性调查是能够…的此外，为了探测目标航道和着陆区，探地雷达的结果也得到了电磁方法(EM调查)的确认。GPR和EM调查进行了几次，在这些调查中，场地具有不同的地面条件(例如土壤水分条件)。研究发现，考虑到场地的气候和自然环境，理想的土壤条件最有利时，才能获得成功的测量结果。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(斋藤市，宫崎县)，东高遗址的古政府遗址(高崎县，群马)，以及下田寺遗址(Himeji，兵库县)。Yoshinogari遗址(佐贺金崎町)的陶盆埋葬也进行了调查，调查结果表明，GPR不仅能够检测到这些埋葬，而且数据表明，这些埋葬还可以分为幸存的完好墓盆和倒塌的墓盆。这些研究的总体结论是，探地雷达可以成功地应用于大范围考古遗址调查的研究。较少

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
