摘要
Abstract
When the active jamming enters the main lobe,the directional diagram of traditional adaptive beamforming causes serious waveform distortion,forms the nulls in the main lobe,and the level increase in sidelobe.Taylor estimation was used to obtain an estimate of the covariance matrix,to construct a fea-ture projection matrix through feature decomposition,and to construct a convex optimization model with deepening sidelobe nulls to solve the adaptive array weight vector.Finally,the proposed method was ex-perimentally simulated and compared with the methods of preprocessing based on blocking matrix and pre-processing based on feature projection,to prove the advantages of the main lobe interference suppression method based on Taylor estimation.关键词
