Abstract

Summary

Accurate object detection and identification is a requirement when mapping the seafloor, either for environmental or commercial purposes. Synthetic aperture sonar (SAS) is improving the ability to correctly identify objects with greater ranges, higher resolution, and faster collection speeds. Kraken Robotics’ MINSAS has been used in harbor surveys to identify debris, and the 3 x 3.33 cm resolution provides very clear images, resulting in definitive object identification and classification. SAS imagery also provides information on object or seabed composition, distinguishing between dense or soft materials based on the intensity of signal returns. For example, metals are represented as bright features while non-metals (softer objects or marine life), return softer features with lower intensity values. The ability to accurately identify surface-based debris allows for improved planning of debris removal or remediation work.
