MATLAB Simulation for Wideband Direction of Arrival Estimation

This documentation provides a MATLAB simulation program for wideband direction of arrival (DOA) estimation. The implementation employs the Test of Orthogonality of Projected Subspaces (TCT) algorithm to compute the focusing matrix, which is then utilized by the Multiple Signal Classification (MUSIC) algorithm for spatial spectrum estimation. The simulation includes functions for array signal processing, covariance matrix calculation, and eigenvalue decomposition to enhance algorithm understanding. Detailed comments and modular code structure allow users to modify parameters such as signal bandwidth, array geometry, and snapshot numbers for different application scenarios. The program demonstrates practical implementation aspects including focusing matrix optimization, spatial smoothing techniques, and peak detection algorithms for accurate DOA estimation. Comprehensive documentation accompanies the code to facilitate customization and extension for various research and development requirements in array signal processing applications.
