| 講演要旨(和文) | | 近年，マルチコプターを探査に用いることが期待されている．我々は過去に地表ソース型の空中電磁探査装置(GREATEM1))と地上電磁探査装置(PTDView2))を開発した．今回，これらの技術を活かして，マルチコプターを用いた小型軽量化した空中電磁探査装置(M-GREATEM)を開発した．M-GREATEMの検証実験としては，空中電磁探査は1次元解析により，また，高密度電気探査は2次元解析により，ほぼ同一測線上にて比抵抗断面を得た．本研究では両者の比抵抗断面を比較検討した．そして，M-GREATEMにより測定された比抵抗断面が大地の比抵抗構造を捉えていること，かつ，その探査方法が，広域の探査を，迅速かつ簡便に実施できることを確認した． |

| | 講演要旨(英文) | | In the near future, it's expected to use a multicopter for geophysical exploration. We have already developed GREATEM(Grounded electrical source airborne transient electromagnetics) and PTD (Portable time-domain)View system. This time, we developed a compact and lightweight airborne electromagnetic exploration instrument(M-GREATEM) using a multicopter by applying this technology. As verification experiments of M-GREATEM, about similar measuring lines, data of M-GREATEM was analyzed by 1 dimension and data of High-density electrical prospecting was analyzed by 2 dimension. In this study, we compared and examined the resistivity structures which were analyzed by both methods. The result comfirmed that the resistivity cross sections analyzed by M-GREATEM capture the features of the resistivity structure, and that this exploration method can measure a wide area quickly and conveniently. |
