Low-cost Expedition-ready Multibeam System

  09/03/2010
A new cost-efficient sonar bridging the gap between singlebeam echosounders and high-resolution multibeam sonar systems is the HydroBat, a multibeam system operating at 160kHz and covers a swath of 120°. Rich Lear at RESON explains the significance: "A task that used to take a week with the old singlebeam echosounders, takes only three days with this new multibeam HydroBat."
 
Low-cost Expedition-ready Multibeam System

Designed to be simple and reliable, the new HydroBat from RESON is ready to meet the demands of serious hydrographic users in harbours and ports. Former software developer, Simon Barchard, states: "A really neat feature is the ability to run a fully functional survey software package on the sonar processor".

 

Commenting on the way HydroBat is optimised, the R&D engineering team points out that the product has been specifically designed for surveyors looking to make the transition from singlebeam to multibeam sonar, with the minimum of investment but without sacrificing product quality and performance."

 

HydroBat is being demonstrated during Oceanology International 2010 in London, 9th to 11th March.

Hydrographic Survey for Riverbed Erosion

 

U.S. Geological Survey were 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 analyzes 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. 

Gage height at the Williston gage was approximately 27.65 feet when this video was taken. Additional information about the USGS streamgage at Williston is available at http://waterdata.usgs.gov/nd/nwis?program=nwisman&site_no=06330000
