AbstractIn order to obtain a preliminary overview on the effectiveness of the underwater anti-divers magnetic-acoustic “MAC System”, we have developed a synthesis between the results coming out from the two different subsystems (magnetic and acoustic), based on two different models, during two different test sections. The section covered by the magnetic component, measured near the NURC dock (La Spezia, Italy) in very noisy port condition, has been remodeled on the sea bottom profile of the access channel to the Italian Navy Base in La Spezia, which presents environmental electromagnetic noise compatible with the NURC’s one. In this entrance way has been executed an acoustic port protection experiment, too. The two different covered sections (magnetic and acoustic) have been merged to obtain an integrated synthetic model of the accuracy of the MAC System. The results have pointed out a remarkable increase of the antidivers covering effectiveness, in particular in the boundary zone of the access way to be protected: the confidence of the MAC System can be considered quite 1 and higher in respect to the sum of the confidence of the two subsystems.
