This article discusses digital beam array processing and provides a simple simulation of MVDR beamforming for planar arrays. In this process, digital beam arrays perform signal processing and analysis on received signals to achieve beamforming. This beamforming technique enhances the directivity of the array's reception pattern, significantly improving signal strength and quality. The implementation typically involves calculating the covariance matrix of received signals, applying diagonal loading for numerical stability, and computing optimal weights using the MVDR criterion through matrix inversion operations. Common functions used include eigenvalue decomposition for interference analysis and steering vector calculations for direction specification. Consequently, digital beam array processing finds extensive applications in communication and radar systems. We hope this technical explanation proves helpful for your understanding!
