研究題目

3D GPR survey for Archeological investigations in Mongolia

研究内容

Sato lab has various research activities based on radar technology in many countries. Due to the geological condition and climate uniqueness of the survey site, the penetration depth of the radar signal can vary in a high range. We were involved in a number of archeological projects and requested to conduct a GPR survey in Japan. However, we could not clearly visualize subsurface structures and buried objects in some survey sites due to the high attenuation of subsurface layers and soil inhomogeneity. Based on the Sato lab experience of GPR survey in Mongolia for more than 20 years, GPR measurement always showed deep and clear subsurface structures, including a fault, groundwater table, horizontal layers, etc. This fact is caused by dry soil condition which allow a radar signal to penetrate deep.
To investigate man-made buried objects, especially archeological investigations, GPR is one of the best methods due to its non-destructive data acquisition. Sato lab has very strong GPR facilities both software and hardware. We planned to conduct a 3D GPR survey at an archeological site, in Mongolia. Since Sato lab has developed 3D Migration algorithm, we apply a 3D migration for regularly or irregularly acquired GPR data at any topographic condition. We planned to acquire GPR data with different antenna frequencies, including 100 MHz and 500 MHz antenna. The nomadic dynasty of Mongolia had great influence on history. We planned to conduct a GPR survey at “Shoroon bumba”archeological site which is located at Bayannuur soum, Bulgan province. “Shoroon bumba”is a group of burial mounds historically belonging to the 7^th to 8^th centuries AD.
