Acoustic systems are recognized to be remote sensing tools that measure efficiently sediment properties and seabed morphology [1].Single beam, multibeam echosounder and sidescan sonar systems are commonly used to characterize seabed type by respectively analyzing echo strength returns, backscatter (BS) angular response, and texture analysis. Multibeam  (and interferometric sidescan ) systems  have the great advantage to measure the bottom bathymetry hence the true grazing angle at least in the across track direction.

First investigation ([3],[4]) have shown the high potential of multiswath multibeam system. With the 3D steerable swath capability, the bidirectional BS angular response can be recorded on each insonified soundings. This presentation will emphasize recent advances in processing using the  full multiswath multibeam capabilities.</p><p> </p><p>References:</p><p>[1] John T.

Seabed mapping has become vital for effective management of marine resources. An important role in moving towards ecosystem based management is played by the defining and understanding of the relationships among marine habitat characteristics, species distribution and human activities. Mapping seabed characteristics by means of remote acoustic sensing, using seabed seismic profiling, sidescan sonar, or echo-sounder based classification systems, is becoming of increasing importance. This paper gives a brief overview of existing marine habitat mapping technologies and their recent developments. In singlebeam echo-sounders, using multiple frequencies will be useful in classifying the seabed. It must be observed that the resolution of a sidescan sonar with narrower along-track beam width and higher range sampling rates will be better than a multi-beam echo-sounder, although the specifications of the newer systems are much improved. Airborne LIDAR bathymetry is very useful for shallow water seabed mapping, particularly in challenging rocky areas vulnerable for ship-based mapping operations. Seabed maps are essential in any case for siting of bottom mounted energy devices. The utmost care should be taken at all stages of the classification process, such as input data, control of interfering factors, seabed acoustic attributes, classification methods and ground-truth observations.
