Simple Underwater Acoustic Beamforming with MATLAB Implementation

This project implements a basic underwater acoustic beamforming program using MATLAB. The core functionality involves localizing beam incident angles through acoustic wave propagation and reflection calculations. The program processes hydrophone array signals using delay-and-sum beamforming algorithms, where time delays are applied to each sensor channel to steer the beam toward specific directions. Key functions include calculating phase shifts based on array geometry, applying weighting windows to reduce sidelobes, and computing angular spectra through Fast Fourier Transform (FFT) operations. The system analyzes processed acoustic signals to determine target positions with improved accuracy. Parameters such as array spacing, sampling frequency, and beam steering angles can be adjusted through configuration variables for optimization. This implementation demonstrates practical applications in marine exploration, underwater communication systems, and sonar target detection by providing customizable beamforming capabilities with real-time processing potential.
