Where can a side scan sonar be mounted?
Side scan sonar transducers may be towed from a surface vessel or mounted on the ship’s hull. The intensity of the acoustic reflections from the seafloor of this fan-shaped beam is recorded in a series of cross-track slices.
Will a side scan work through hull?
No. Side Imaging transducers have beams that shoot out to the side of the transducer therefore they cannot be epoxied into the hull and work properly. In addition, we do not recommend this type of installation for Down Imaging. Shooting through the hull of a fiberglass boat causes the signal to be lost.
What is side scan sonar used for?
Side scan sonar is a category of active sonar system for detecting and imaging objects on the seafloor. The multiple physical sensors of the sonar — called a transducer array — send and receive the acoustic pulses that help map the seafloor or detect other objects.
What is a disadvantage to the side scan sonar?
System Disadvantages: • The length of tow cable length needed to get sonar to depth. (typically 3/1 or 4/1 ratio when “towfish” deployed) • Requirement to keep the sonar head towed in a straight line. and at a fixed speed. • The ability to position a target when a long length of tow cable.
Which is better hull mounted or towed side scan sonar?
With the advent of inexpensive hull mounted sonar systems such as the Humminbird® Side Imaging® sonar and professional software, users want to know if this unit will be as effective as a towed side scan sonar system. The answer is absolutely, positively, maybe!
What kind of sonar is a side scan sonar?

How are hull mounted sonar systems used in search and rescue?
Autonomous Underwater Vehicles (AUV’s) and remote-control surface vessels such as Sonar EMILY have been introduced and many Search and Rescue (SAR) organizations have found hull mounted systems, originally developed as fish finders, to be effective, economical alternatives under certain conditions.
What kind of sonar system does a USV use?
