Abstract

In this contribution, we present some results achieved in the archaeological site of Le Cesine, close to Lecce, in southern Italy. The investigations have been performed in a site close to the Adriatic Sea, only slightly explored up to now, and where the presence of an ancient Roman harbour is alleged on the basis of remains visible above all under the current sea level. This measurement campaign has been performed in the framework of a short-term scientific mission (STSM) performed in the framework of the European Cost Action 17131 (acronym SAGA), and has been aimed to identify possible points where future localized excavation might and hopefully will be performed in the next few years. Both a traditional elaboration and an innovative data processing based on a linear inverse scattering model have been performed on the data.

Highlights

  • Ground Penetrating Radar (GPR) is a useful tool to study and document cultural heritage sites [1,2,3]

  • The system exploited for this was a RIS Hi-mode pulsed GPR manufactured by IDSGeoradar equipped with a dual antenna with nominal central frequencies at 200 and 600 MHz

  • We have presented the results of a GPR measurement campaign performed at the archaeological site of Le Cesine, where several remains suggest the presence of an ancient Roman harbour

Summary

Introduction

Ground Penetrating Radar (GPR) is a useful tool to study and document cultural heritage sites [1,2,3]. Thanks to the shifting zoom, we will apply an inverse scattering algorithm to three electrically large sets of data and we will create depth slices based on this procedure We will do this in relation to the archaeological site of Le Cesine, close to the Adriatic. These recent archaeological investigations have opened up an intriguing problem regarding the reason why two Roman harbours would have been built so close to each other This is not the focus of the present paper, but witnesses the cultural relevance of the performed investigations.
