f Enhancement and filtering of magnetic data in archeological sites

This work focuses on exploration of an archaeological site by magnetic survey. The aim of the survey is to evidence the presence of structures connected to an ancient Italic civilisation by means of new techniques for anomaly residuation and signal enhancement. The ancient settlement is located near S. Maria a Vico village, placed on a terrace of fluvial origin. The terrace is engraved in travertines covered by alluvial sediments and ash pyroclastic of Somma-Vesuvius and Flegrean Fields. In these sediments, altered by the weathering and about 3 meters thick, the remnants of proto-historical settlement to be investigated are buried. S. Maria a Vico is about 10 km far from Pontecagnano, site of a very important archeological deposit associated to the "Villanoviana" culture (Peninsular Italy, IX - VII century B. C.). Although the ancient site of S.Maria is associated to the "Tombe a fossa" culture, it was influenced by Villanoviana culture, being linked to the Etrurian-Campanian area and to the Greek colonies of the Ionian Sea. Excavation works, carried out in 1986 and 1991, did not allow to get clear elements about organization of the ancient settlement. Most of the remnants allow to estimate an age between VII and VI century B. C to the settlement.
