High-Resolution Bearing Estimation with MVDR Algorithm for Array Signal Processing

This MATLAB-based MVDR (Minimum Variance Distortionless Response) program is designed for high-resolution bearing estimation in array signal processing applications. The implementation offers valuable reference material for professionals working in related fields. The program enables users to process array signals and achieve high-precision direction of arrival (DOA) estimation, which is critical for target localization and signal source identification tasks. The core algorithm utilizes covariance matrix estimation and inverse computation to minimize output power while maintaining distortionless response in the desired direction. Key implementation aspects include: - Array manifold vector construction for specified geometry - Sample covariance matrix calculation from received signals - Regularization techniques for numerical stability - Beamforming weight computation using matrix inversion MVDR processing effectively enhances spatial resolution and estimation accuracy compared to conventional beamforming methods. This makes the program particularly useful for researchers and engineers requiring advanced array signal processing capabilities for high-resolution bearing estimation applications. The code structure follows modular design principles, allowing easy adaptation to different array configurations and signal scenarios.
