Overview of Beamforming Research
Abstract— Beamforming is one of the core technologies in the field of array signal processing. It is widely used in different fields, especially in wireless communication, radar, sonar, medical engineering and microphone voice array processing. For beamforming, the most important problem is the selection of optimal weighting coefficient and the comprehensive consideration of robustness. On this basis, this overview classifies and summarizes beamforming algorithms in recent years, which can be divided into five categories: based on covariance matrix reconstruction algorithm, based on steering vector correction algorithm, based on second-order cone programming algorithm, based on broadband subarray algorithm, based on neural network algorithm. Finally, the future development trend of beamforming technology is discussed
