New Vertical Array for Acoustic Communications Studies in Trondheim Fjord

Chelsea Technologies Group has delivered a novel acoustic array to the Norwegian University of Science and Technology (NTNU). The six metre long, oil filled array, houses six omni directional identical hydrophones. The array is designed to be suspended from a small boat or buoy to depths of 100 metres.

Dr Zhang Guosong of NTNU commissioned Chelsea to build the custom hydrophone array to conduct novel underwater acoustic experiments in the Trondheim fjord.

Dr Guosong and his team are looking to exploit spatial diversity in order to research novel communications and acoustic propagations. Chelsea has previously supplied a range of acoustic transducers and hydrophones to NTNU.

Chelsea Technologies Group has 50 years experience in the design and manufacture of underwater acoustic transducers including hydrophones, projectors, pingers and sidescan sonar arrays.

They are also leaders in the design of state of the art systems for calibration, test & performance evaluation of airborne, surface ship and submarine sonars. Come and meet our new acoustics specialist, Kimberley Walrond at Ocean Business.
