Super-directivity sensor arrays are quite promising in target finding, due to their small size and enhanced directivity. An array design method which can build a desired beam pattern using compact multi-pole is presented this paper. The proposed extracts modes of different order from the spatial differentials sound field, square that consists vector sensors having dipole directivities. differential extraction procedure approximated by difference, decreases performance. performance degradations patterns investigated at working frequencies. Simulation analysis show gain robust uncorrelated noise.
