AUV-Based Side-Scan Sonar Real-Time Method for Underwater-Target Detection
Journal of Marine Science and Engineering, 2023 The limitations of underwater acoustic communications mean that the side-scan sonar data of an autonomous underwater vehicle (AUV) cannot be transmitted back and processed in real time, which means that targets cannot be detected in real time. To address
