“…Advances in beam-forming are also being incorporated into 3-D chirp profiling systems (e.g., Gutowski 2005), which employ a two-dimensional array of transmitters and receivers. Such systems require highly accurate knowledge of the platform position and attitude to support the focusing and beam-forming.…”

This paper discusses the basics of acoustic remote sensing (ARS), whereby information may be inferred about the environment through measurements of backscatter. The physical process of backscatter is described with emphasis on the different outcomes that are associated with a variety of common seabed materials. It is shown that the potential information, which can be inferred from measurements of backscatter, depends on the system design. Important system design parameters include acoustic frequency, pulse length, beamwidth, and deployment technique (towed or hull-mounted). The operational deployment of towed sidescan sonar, in particular whether it is towed close to the seabed or towed higher in the water column, can modify the potential utility of the backscatter measurements to habitat mapping.

Offshore 3D-seismic acquisition has been a standard for high-precision structural imaging in the oil and gas industry for many years. Recently this technique has been adapted by only a few teams to the resolution required for archaeological marine investigation. In contrast to sonar techniques, the 3D-seismic method produces images below the sea-floor. We investigate the harbour of the Viking age proto-town of Hedeby in Northern Germany with the SEAMAP-3D system. SEAMAP-3D allows for rapid acquisition and employs an automated data processing sequence. We observe a wealth of archaeologically relevant detail and compare our results with previous work.
