In underwater environments, the detection and recognition of submerged objects or targets play a crucial role in applications ranging from marine research to naval operations and underwater robotics. This project introduces an innovative approach to enhance the accuracy and efficiency of underwater target detection through the utilization of sonar technology and advanced machine learning algorithms. The project leverages the capabilities of sonar systems to emit sound waves into the underwater environment and receive their echoes, creating acoustic images of underwater surfaces and objects. These acoustic images are rich in information but often challenging to interpret accurately. To address this challenge, state-of-the-art machine learning algorithms, including deep learning techniques, are employed for the automatic detection and classification of underwater legitimate or phishing objects. The system's architecture involves the integration of sonar data acquisition, pre-processing, and feature extraction, followed by the application of machine learning models trained on diverse underwater object datasets. By utilizing deep neural networks and other ML techniques, the system learns to recognize and classify various underwater objects, such as Torpedo’s, Weapons, submarines, marine life, and geological formations. The benefits of this project extend to numerous domains, including marine conservation, underwater archaeology, and defense applications, where precise and rapid underwater object detection is essential. By combining sonar technology and machine learning algorithms, this project contributes to advancing our understanding and exploration of underwater environments, ultimately improving the safety and efficiency of various underwater operations.
