Side scan sonar: acoustic image of a pillar 

Contexts in source publication

Context 1

... carefully observing the sonogramms, is possible to identify targets of small size as the pillar in Figure 1 of an ancient coastal villa now submerged, or targets of extended dimensions as the canal walls to ancient Baianus Lacuus in Figure 2. Sonograms are carefully analyzed to identify the archaeological targets and characterize their nature and size. The backscatter signal in an area with rocky bottom and a zone of human constructions (pillar in Figure 1) can be analyzed to detect the difference. ...

Sonograms are carefully analyzed to identify the archaeological targets and characterize their nature and size. The backscatter signal in an area with rocky bottom and a zone of human constructions (pillar in Figure 1) can be analyzed to detect the difference. In particular in Figure 1, the target dimensions are evaluated: 2.8 m N-S and 3.4 m WE, with a height of 1.5 m. ...

Context 3

... backscatter signal in an area with rocky bottom and a zone of human constructions (pillar in Figure 1) can be analyzed to detect the difference. In particular in Figure 1, the target dimensions are evaluated: 2.8 m N-S and 3.4 m WE, with a height of 1.5 m. In Figure 2 the target dimensions are: 60 m N- S and 200 m WE. ...

Context 4

... reconstruction of the morphology of the most important underwater archaeological sites is possible with the acoustic method SSS, with high accuracy in calculating the size of the target. In the case of Figure 1 for example, the SSS survey has allowed the delimitation of the arbour of Roman villa now submerged near a very touristic site and has prevented that this site was covered from the construction of a security barrier. ...

Context 5

... the case of Figure 3, the pillar of the Roman villa submerged (described above in Figure 1) was identified by comparing the acoustic response of pillar with that of the surrounding rock. In particular, the oscillogram of the pillar target (C) is characteristic and very different of the oscillogram of the rock target (D). ...
