Ultra-high Frequency Side-scan Sonar
16/08/2010
EdgeTech has recently developed a new 600/1600 kHz frequency set for their popular 4125 Side Scan Sonar System. This new frequency combination is part of a variety of enhancements that have recently been made to the 4125.
The new 600/1600 kHz towfish was designed specifically for search & recovery, port security and small target identification applications. The customer can now choose between this new frequency offering or the 400/900 kHz 4125 towfish, which is the perfect tool for shallow water survey applications.
Members of the US Geological Survey were filmed while out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyses the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
