Robust Adaptive Beamforming via MEPS-Based Covariance Matrix Reconstruction and Steering Vector Estimation in Space-Polarization Joint Domain for Mainlobe Interference Suppression

Signals
In scenarios where mainlobe interference and steering vector (SV) mismatch coexist, conventional robust adaptive beamforming techniques are prone to main-beam distortion, desired signal self-cancellation, and degradation of output performance. To address
