[eng] In this thesis, the final objective is to detect military
vessels from a distance of 500 metres from an underwater
unmanned vehicle. This research offers a path towards that objective, reaching the election of a magnetometer, the development
of software that can be integrated in the existing one and the
detection of various metallic masses, including two vessels of more
than 10.000 tons. The results are not completely conclusive and
there is still work left to do in further research.
