A modified robust algorithm against large look direction error based on interference-plus-noise covariance matrix reconstruction and steering vector double estimation

Abstract

Adaptive beamforming is one of the most important aspects of array signal processing, which has been widely used in radar, sonar, mobile communications, radio astronomy, and many other fields. However, adaptive beamformers are sensitive to the model mismatch, especially when signal of interest (SOI) is presented in training data or when there are small… (More)
