N2 - A novel adaptive broadband beamforming structure is proposed, where the tapped delay-lines in the traditional broadband beamforming structure are replaced by sensor delay-lines and only one coefficient is required for each of the received sensor signals, In this way, the high-speed analogue tapped delay-lines or digital sampling circuits are not required any more for some broadband beamforming applications and beamforming can be realized by simple analogue circuits. Since there is no temporal information employed for beamforming, it can be considered as a beamforming method with spatial only information. The effectiveness of the proposed method is verified by simulations.
