Detailed Documentation

In this article, we present the MATLAB source code implementation of the MUSIC (Multiple Signal Classification) algorithm, a high-resolution technique for multi-beam systems. The program effectively demonstrates the algorithm's superior resolution capability through visual outputs. MUSIC is a classical algorithm for signal direction estimation widely applied in radar systems, communication engineering, and acoustic signal processing. The core principle involves processing signals received by multiple antennas to estimate direction-of-arrival (DOA) based on phase differences. This implementation features key components including covariance matrix computation, eigenvalue decomposition of the signal subspace, and spatial spectrum peak detection. The source code serves as an educational tool for understanding the algorithm's underlying principles and implementation methodology, while providing a foundation for further research and development in array signal processing.
