Description:
This paper shows the result obtained during the operative test of an anti-intrusion
undersea magnetic system based on a magnetometers’ new self-informed network. The experiment
takes place in a geomagnetic space characterized by medium-high environmental noise
with a relevant human origin magnetic noise component. The system has two different input
signals: the magnetic background field (natural + artificial) and a signal composed by the magnetic
background field and the signal due to the target magnetic field. The system uses the first
signal as filter for the second one to detect the target magnetic signal. The effectiveness of the
procedure is related to the position of the magnetic field observation points (reference devices
and sentinel devices). The sentinel devices must obtain correlation in the noise observations and
de-correlations in the target signal observations. The system, during four tries of intrusion, has
correctly detected all magnetic signals generated by divers.
