| 講演要旨(和文) | | 東北大学では人道的地雷除去活動の効率を高めるために，金属探知機（電磁誘導センサ）に地中レーダ(GPR)を追加したデュアルセンサALIS（エーリス）の開発を続けてきた．本稿では，ALISによる地雷検知技術とカンボジアにおける地雷の検知・除去の実情を紹介した．カンボジアは我が国が長期的に地雷，不発弾の除去に技術的，経済的支援を行ってきた国である．我が国においても沖縄を始め，全国至る所で第2次世界大戦中の不発弾は発見されることがある．こうした問題に限らず，金属探知機による埋設物検知は災害，減災にも役立つ技術であると考えている． |

| | 講演要旨(英文) | | ALIS (Advanced Land Mine Imaging System) is a dual sensor, which combines EMI sensor and GPR. Tohoku University has started the development of ALIS in 2002, and after tests in Cambodian land mine fields, it is now ready to be deployed in mine affected countries. An evaluation test of ALIS was conducted by CMAC (Cambodian Mine Action Centre) for a certificate to use ALIS in mine fields in October 2018. We trained 4 deminers of CMAC, and they demonstrated that ALIS can images typical landmines in Cambodia including PMN-2 and Type-72 in various types of soil very clearly. The EMI sensor can pin-point the location of the buried objects, and GPR can image the targets, which can be used by the deminer to judge the buried object. The test results was good, and the certificate was given to ALIS in January 2019. Since January 2019, two ALIS systems have been deployed in mine fields in Cambodia. In this paper, we introduce the technical performances of ALIS, and then reports the recent activities of ALIS in Cambodia. |
