Research on wideband beamforming with constant beamwidth using vector sensor array

In this paper, using broadband beamforming sub-array synthesis method carried out theoretical calculations and simulation analysis by a multiple vector-sensor array. The results show that using sub-array synthesis method of constant beam width of the theory is simple and can greatly reduce the computation, while vector sensor array using of broadband constant beamwidth beamforming method are superior to conventional acoustic pressure array in spatial gain, aperture of array and anti-port/starboard ambiguity property etc.
