Abstract
The performance of a two-element broadband beamforming structure with sensor delay-lines (SDLs) attached is studied for two adaptive implementations, in terms of the direction of the interfering signals, the inter-spacing between delay-line sensors and the length of the SDLs. Compared with the conventional broadband beamformers with tapped delay-lines (TDLs), the SDL based structure has a better performance in two aspects: its output signal to interference plus noise ratio (SINR) drops less as the inter-delay within delay-lines increases; with the same number of delays and weights it can achieve a better performance than the TDL one.
