一种稳健的二维自适应波束形成算法
A robust two-dimensional adaptive beamforming algorithm
摘要
Abstract
The existing two-dimensional robust adaptive beamforming algorithms only have simplex function,and the multifunctional robust beamforming algorithms are scarce.Aiming at all the cases which lead to performance degradation,an improved two-dimensional robust adaptive beamforming algorithm combined with spatial spectrum estimation technology was considered.Firstly,a new two-dimensional spatial spectrum estimation algorithm was proposed.This method utilized four one-dimensional spatial spectrum estimations to estimate the directions of the signals,and the modified MUSIC algorithm was used to estimate the coherent signals.Then the weight vector was calculated via virtual interferences constructed with the aid of angle information.Simulation results show that the algorithm simultaneously has the advantages of the adaptive beamforming technology and the spectrum estimation technology,and has sufficient robustness for steering vector error,interference angle of arrival mismatch and signal interrelation.关键词
