摘　　要：基于声矢量阵提出了一种宽带恒定束宽波束形成方法,该方法将宽带方位估计中的空间重采样思想应用到恒定束宽波束形成器设计之中,并通过计算机仿真实现了宽频范围内-3dB主瓣宽度的恒定,这对于进一步研究声矢量阵宽带波束域高分辨方位估计技术是十分重要的。A method for broadband constant beamwidth beamforming based on acoustic vector array is presented. The concept of spatial sampling in the wideband DOA estimation is employed to design the constant beamwidth beamformer. Then the spatial resampling method is introduced to achieve the constant width of main lobe in -3 dB, which is important for the further study of the wideband beam space high resolution DOA estimation technology based on acoustic vector array.
