| Research Abstract |
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

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
