| Definition | Also known as a DS 3G. A deep water multi-beam echo sounder which uses operating frequencies between 14 - 16 kHz to determine bathymetric depth. It can generate 320 receive beams per ping which can be modulated using beamforming into 960 soundings per swath. It also generates 2 swaths simultaneously per ping. The third generation uses not only continuous wave (CW) pulses, but also frequency-modulated (chirped) pulses and Barker coded pulses which result in 20 - 50% more swath width. Available transducers are planar arrays with beam resolutions of 0.5x1, 1x1, 1x2 and 2x2 degrees. The system has a depth range of 10 - 11,000 m. This is the 3rd generation of the Hydrosweep DS. Atlas Hydrographic is now part of the Teledyne Reson group. | ||
