| 講演要旨(和文) | | Van Khan Tooril遺跡は、ウランバートル市の西30kmにあるTuul川沿いのBlack Forestにあり、13世紀に書かれた、”Secret History of the Mongols”という本の中にも何度か記述がある古い都市である。ここでは、モンゴル政府の援助で、2006年からVan Khan Tooril遺跡の発掘が始められている。我々は、Van Khan Tooril遺跡で500MHzのシールドアンテナ、RAMAC/GPRを用いて、20cm間隔の線の上で、5cm毎の測定を、3つのグリッドで行った。そして、fkフィルタ、バンドパスフィルタを適用し、あるしきい値を用いて、信号処理を行った。そして、全てのグリッドで、強度のスライスマップは深さ10cmに相当する、2nsの間隔で作成した。その結果、反射プロファイルはレンガと石造りの基礎の構造を示した。 |

| | 講演要旨(英文) | | GPR have been proving very successful tool for archeological exploration and provide reliable information for further excavation. The Van Khan (Wang Khan) Tooril's ruin is located along Black Forest of the Tuul River 30km west of Ulaanbaatar city. The Black Forest of the Tuul is mentioned several times in the Secret History of the Mongols, the thirteenth-century account of the rise of the Mongols and the life of Genghis Khaan. The Mongolian archeologists have started to excavate Van Khan Tooril's ruin from 2006 by Mongolian government support. The archaeologists were requested to rebuild the ruin as in the ancient period. The three grids were collected in Van Khan Tooril's ruin by RAMAC/GPR 500MHz shielded antenna with a 20cm cross-line spacing and 5cm in-line sampling interval. We have applied fk-filter, bandpass filter and used threshold value. After signal processing reflection profiles show brick and masonry foundation. In all grids amplitude slice-maps were constructed in 2ns slices, each of which is approximately 10cm thickness of the depthwise. |
