Comparative study on adaptive digital beamforming techniques

Adaptive digital beamforming is also known as spatial filtering technology. By adaptively adjusting the weight of the array element to change the direction of the received signal, the main lobe points to the desired signal, and a null is generated at the interference signal. Adaptive digital beamforming technology has a strong suppression effect on spatial interference. This paper summarizes beamforming technology, introduces the beamforming criteria and their advantages and disadvantages, lists three classical adaptive digital beamforming algorithms, and quantitatively analyzes the differences between the three algorithms. The computational complexity of each algorithm is innovatively compared, and the development of airspace anti-jamming technology is proposed.
