| | Abstract | | In order to investigate the electromagnetic response of UXO, series of experimental surveys using GEM-3 were carried out. At first, comparative experiments in seawater and air using a water tank were carried out in order to assess how the media influences the response characteristics. It turned out that the both patterns of electromagnetic response were basically similar though slightly different signal strength. Then onshore experiments were carried out to assess the electromagnetic response on various metal objects in positions, including UXOs. Each categorically unique type of metal object reveals an intrinsic spectrum pattern of electromagnetic response. It suggests that this technique will be useful in detecting UXO once the target spectrum pattern is known. |
