摘要
The authors propose a novel approach to designing a partially adaptive array using direction-of-arrival (DOA) estimation and a null steering technique. The DOAs of the interferences are estimated using some selected outputs of the signal blocking matrix to form the ensemble signal blocking correlation matrix. The eigenvector corresponding to the minimum eigenvalue of the ensemble signal blocking correlation matrix is then used to form nulls in the spatial spectrum which are corresponding to the incident angles of interferences. Synthesised nulls are then placed in the mainbeam to cancel all the interference signals.
