Abstract
The wide band sonar has been designed to provide a versatile platform from which to interrogate the seabed. Using a parametric array provides a wide bandwidth and avoids boundary interactions from sidelobes, making the system ideal for measurements in coastal waters. Another key feature of the system is that the sonar is remotely controlled from a research ship via an RF radio link. This permits a wide range of experimental geometries, minimizes the risk of acoustic interference from the ship and prevents ship motion from compromising array stability.
