MATLAB Implementation of Broadband Beamforming with Focus Matrix Method

This is a MATLAB-implemented broadband beamforming program. Beamforming represents a signal processing technique that enables receivers to focus on signals arriving from multiple directions, thereby enhancing signal strength. Specifically, this program utilizes a focus matrix to form beams, where the focus matrix is determined by the receiver's position and the direction of the target signal. The core algorithm involves calculating steering vectors based on array geometry and implementing time-delay compensation through phase shifting in frequency domain processing. When executing this program, users can process various input signals and generate corresponding output results. The code structure includes key functions for array configuration setup, focus matrix generation, and beam pattern visualization. Users can modify parameters such as array element spacing, signal bandwidth, and target directions to adapt to different application scenarios. The implementation employs Fourier transform techniques for wideband processing and incorporates windowing functions to control sidelobe levels. This program serves as an educational tool to help users better understand and apply broadband beamforming technology, with practical applications in radar systems, wireless communications, and acoustic signal processing. The modular code design allows easy extension for advanced features like adaptive beamforming and interference suppression algorithms.
