Abstract

Adaptive nulling methods under multiple constraints for Digital Beamforming (DBF) of Uniform Linear Arrays (ULA) are proposed, which is studied in three aspects: with main lobe constraint only, with main and side lobe constraints, with main and side lobe constraints and given nulls constraints. Optimum weight vector of DBF is derived by Lagrange multiplier approach and calculated with sample matrix inversion algorithm. Effectiveness and correctness of the proposed methods are verified by computer simulations.
