Abstract

The performance of the conventional broadband adaptive beamforming methods degrades severely in scenarios with moving interference. Moreover, due to the inconsistency of mainlobes width at different frequencies, the conventional methods also deteriorate when the target direction differs with the look direction. Therefore, a robust broadband adaptive beamforming method with constant beamwidth for moving interference suppression is proposed. In the proposed method, a taper matrix is constructed by adding two virtual interferences arranged at the two sides of each original interference. Then the array covariance matrix is reconstructed based on the taper matrix and the sample covariance matrix. Meanwhile, the spatial response variation (SRV) constraint is applied to guarantee a constant beamwidth over the entire frequency band. Finally, the adaptive weight vector for null broadening and constant beamwidth is calculated by the Lagrange multiplier method. The effectiveness of the proposed method has been verified by numerical simulations.
