Abstract

In this work, we propose a new and efficient algorithm to mitigate the signal look direction error problem in adaptive beamforming without broadening the main beam. The algorithm exploits a reference lobe in the region of signal look direction error. This reference lobe is the main beam of the generalized sidelobe canceller when there is no direction of arrival mismatch for the desired signal. The desired pattern is forced to follow the reference beam in the region of signal look direction error by utilizing multiple additional constraints. Simulations are performed in MATLAB to check and test the validity of the proposed algorithm on the basis of different scenarios.
