一种改进的基于LC-GSC的主瓣干扰抑制方法
An Improved Mainlobe Interference Suppression Method Based on Generalized Sidelobe Canceller
摘要
Abstract
According to the linear constraints generalized sidelobe canceller ( LC-GSC ) , the adapted pat-tern suffers much distortion ( distorted mainlobe and high sidelobes) , when there exists main lobe interfer-ence. An adaptive beam forming based on blocking matrix data-preprocessing is proposed, which is an im-provement of linear constraints generalized sidelobe canceller. Firstly,a blocking matrix is constructed to cancellthe mainlobe interference, then beamforming based on the linear constraints generalizes sidelobe canceller, which effectively solves the problem of beam deformation while suppressing the mainlobe inter-ference. The method has been proven to be effective by the computer simulation.关键词
