Abstract: For the suppression of rapidly moving interferences in wideband beamforming, an adaptive null broadening method is proposed. In the proposed method, the taper matrix is calculated by adding virtual interferences around original interferences. Then, based… read more here.

Abstract: In this paper, a procedure for the null broadening algorithm design with respect to the nonstationary interference is proposed. In contrast to previous works, we first impose nulls toward the regions of the nonstationary interference… read more here.
