Some widely-used imaging sonars, including Dual-Frequency Identification Sonar (DIDSON) (Belcher et al., 2002), Teledyne BlueView Sonar (Guerneve and Petillot, 2015) and adaptive resolution imaging sonar (Shahrestani et al., 2017), can …

An imaging sonar builds a picture (a) and (b) via rotation of the head (i.e., mechanically scanning) or (c) and (d) with motion through the water (i.e., side scan).

Sound Metrics imaging sonars transmit sound pulses and convert the returning echoes into digital images, much like a medical ultrasound sonogram. The advantage is that they can “see” what’s going on through dark or turbid (cloudy) water in zero visibility conditions.

With continuous technological advancements, software and hardware compatibility, portability and overall ease of use, IMAGENEX sonar systems set the industry standard as the most specified sonar systems world wide.

Apr 1, 2021 · Three-dimensional (3D) imaging sonars are becoming increasingly important for ocean investigation and exploitation. To date, 3D imaging sonars employ a conventional beamforming technique popularly to reconstruct underwater 3D acoustical images.

High-Resolution 360° Profiling Sonar for Subsurface Inspection. ...nced profiling sonar designed to deliver 360° subsea imaging for tunnel and cave inspection.... An advanced 3D multibeam scanning sonar for high-resolution underwater imaging.

The imaging sonar is a useful substitute for a positioning system on an ROV. Without an imaging sonar, an ROV relies on traveling underwater to bring new targets into view. With an imaging sonar, instead of traveling it is more useful to spend some time with the vehicle sitting on the bottom while the sonar scans the surrounding area.

Sonar tomography is a technique to obtain a two-dimensional image of an un-derwater object using a sequence of one-dimensional images, or `projections', of the object of interest. We discuss sonar tomography in a detailed manner and compare the performance of two important `back-projection algorithms' commonly used in tomography.

Aug 31, 2022 · The ISS360 was developed to be the most compact, mechanically scanned imaging sonar in the world. Highly compact with a weight of 0.37kg/0.82lbs in air ensures that the ISS360 is exceptionally easy to integrate onto all underwater vehicles …
