Misure geomagnetiche cinematiche in alta definizione in aree marittime

Abstract

This work is about the experimentation of a new methodology using a proton magnetometer to find artificial sources (as a wrecked ship) at any depht with the highest resolution. Such methodology, called Nottom Reduction (BTM) (Faggioni et al.), adopts a "high definition" procedure in order to strongly decrease the indetermination of the point of measure. The BTM method includes three steps: high definition geomagnetism, temporal correction and bottom reduction. The signals sampled in space (x,y,z) and time (t), are subsequently analyzed in frequency fields: f(s,t)---f(s,w)
