[0002] Side-scan sonar is widely used in underwater topographic surveying, capable of identifying underwater micro-topography and underwater objects. It has advantages in underwater topographic surveying and underwater archaeology (target identification). In recent years, with the rapid application of unmanned surface vessels (USVs) in marine surveying, side-scan sonar has gradually become smaller, making it easier to mount on USVs for underwater topographic surveying. To adapt to this change, auxiliary measurement devices have also changed. Currently, most auxiliary measurement devices for USV side-scan sonar are provided by surveying equipment manufacturers. These devices not only have poor versatility, but their materials are also too thin, making them prone to shaking under water resistance during measurement, which affects the quality of the collected data.
[0003] To address these issues, we propose a side-scan sonar measurement auxiliary device for a catamaran unmanned surface vessel. Utility Model Content
