“…Both the prototype and the commercial system belong to the Laboratory of Applied Geophysics to Archaeological and Monumental Heritage IBAM-CNR. At the moment, it is possible to compare the performances of both systems on several areas of interest, at the renaissancebaroque chapel of the ex hospital of the Holy Spirit in Lecce ) and the area of the "cryptoporticus" within the Messapian and Roman archaeological site of Egnazia (Caggiani et al 2012;Persico 2014). Both indoor measurements in historical monuments (Conyers 2004;Piscitelli et al 2007;Castaldo et al 2009;Kadioglu 2010;Persico et al 2010;Piro and Campana 2012;Soldovieri et al 2012;Goodman and Piro 2013) and outdoor campaigns in archaeological sites (Conyers and Goodman 1997;Ranalli et al 2004;Pieraccini et al 2006;Masini et al 2007;Masini et al 2010a,b;Calia et al 2012;Leucci et al 2012;Utsi 2012) are of great interest for GPR prospecting and the number of case histories in both situations is endless.…”

Some results achieved from a reconfigurable stepped frequency GPR system will be presented. The aim is to show the possibilities of a reconfigurable architecture for a GPR system within the noninvasive prospecting of the Cultural Heritage. In particular, two sites (indoor and outdoor, respectively) have been chosen, in order to test the system in different situations that pose different problems. The same sites have been prospected also with a commercial pulsed system, in order i) to work out a comparative heuristic analysis and ii) to plan possible future advancements improving the reconfigurable system.

Geophysical and Archaeological Characterization of a Modest Roman Villa: Methodological Considerations about Progressive Feedback Analyses in Sites with Low Geophysical Contrast

The low contrast in physical properties of archaeological elements compared to the host soil is a common drawback in geophysical surveys applied to subtle archaeological sites because those contrasts are usually what are being measured by most instruments. Furthermore, when archaeological elements and construction remains are placed within the same package of materials, differentiation of each can make the interpretation of geophysical data sometimes difficult. In this work we propose a dynamic, integrated approach for the characterization of an archaeological site with simple Roman construction materials in order to evaluate methodological considerations in the evaluation of this kind of sites. This approach includes: (i) a preliminary evaluation of construction material characteristics, according to the background provided by the historical and geographical context and from previous excavations, (ii) measurements of magnetic susceptibility of archaeological and natural materials in the site for direct modelling of the expected anomalies; (iii) a geophysical survey including magnetometry, multifrequency electromagnetic (EM) method and ground penetrating radar (GPR) (100, 250 and 500 MHz centre frequency antennas); (iv) geophysical data evaluation for planning subsequent systematic surveys; (v) dynamic interpretation of geophysical results through careful data evaluation of all previous steps. The final archaeological model from geophysical data has been successful due to the manner of data interpretation looking for orthogonal patterns of geophysical anomalies that were hypothesized to be subsurface walls. Modelling was then followed by archaeological excavations consisting of three trenches where the walls were exposed. The integration of geophysical data with excavations has permitted to evaluate significance of the different geophysical analysis and to identify their archaeological meaning. The proposed sequential methodology represents an innovative manner of analysis (i) in subtle sites where construction remains are scarce and the absence of well‐defined geophysical contrasts can limit the results of usual surveys and (ii) to increase the efficiency in the evaluation of more extensive survey areas.

“…Since anthropogenic features, such as kilns, walls, roads, pits, ditches, tiles, etc., often have different magnetic properties from the surrounding soil, this method can be effectively used to detect them (e.g. Becker, ; Johnson, ; Aspinall et al ., ; Ciminale and Gallo, ; Caggiani et al ., ; Caldara et al ., ). Modern instruments and current appropriate procedures for data acquisition, processing and visualisation enable detection of even very subtle anomalies (down to hundredths of nanotesla in the case of buried post‐holes).…”

Archaeological remains are very often buried under uneven soil of agricultural fields crossed by rather parallel furrows and ridges. Consequently, ploughing in a magnetic survey might produce a repetitive, quite regular, linear noise in the data, which could impede optimal recovery of the archaeological magnetic anomalies; depending on the acquisition line orientation, this noise may show as an oblique, vertical or horizontal pattern in the magnetic maps. Several studies have tested and verified methods for oblique ploughing minimization, but, to our knowledge, no procedures regarding the vertical and horizontal types of noise have been published. The present research proposes a procedure to filter each type of ploughing effect through an algorithm working in the wavenumber domain. The procedure produces images with a considerable reduction of the noise in any direction, resulting in enhanced visibility and readability of the archaeological anomalies. Figure 6. Masks for cases of (a) horizontal ploughing; (b) vertical ploughing; (c) oblique ploughing; (d) combination of cases (a) and (b); (e) combination of cases (b) and (c).
