This research aims to enhance the accuracy of Direction of Arrival (DOA) estimation using hydrophone arrays through the application of beamforming methods, particularly focusing on the Delay and Sum Beamforming technique. The study follows a systematic approach, utilizing Matlab for signal generation, analysis, and testing, accompanied by power plots. It also includes a series of steps for the analysis and testing of Delay and Sum Beamforming. The investigation compares traditional DOA estimation methods with Delay and Sum Beamforming and proposes future enhancements, such as exploring alternative beamforming techniques and potential applications of advanced methods like Deep Neural Networks.
