Detailed Documentation

We can employ the MUSIC (Multiple Signal Classification) algorithm for spectral peak search, which efficiently locates peaks in the spatial spectrum of simulated signals. This algorithm operates by performing eigenvalue decomposition on the signal covariance matrix to separate signal and noise subspaces, then constructing a pseudo-spectrum through orthogonal projections. Key implementation steps include: 1) Calculating the covariance matrix from input signal snapshots 2) Applying eigenvalue decomposition to obtain noise eigenvectors 3) Scanning azimuth angles to compute spatial spectrum peaks The algorithm's effectiveness in signal processing enables detailed analysis of signal characteristics through peak identification. By examining spectrum peaks, we gain insights into signal directions-of-arrival and spatial properties, supporting advanced research applications in array processing and spectral estimation.
