摘要
针对平面点圆声基阵的宽带探测性能提升需求,描述了恒束宽波束形成方法,研究了平面点圆声基阵的恒束宽波束形成方法,并对平面点圆声基阵的波束形成算法进行了优化与仿真分析。相较于常规的点圆声基阵常规波束形成,恒束宽波束形成可以降低系统的旁瓣,大幅提升了系统的整体性能,在工程设计上具有一定的应用意义。
In order to improve the broadband detection performance of planar point circular acoustic array,the constant beam width beamforming method is described,and the constant beam width beamforming method of planar point circular acoustic array is studied,and the beamforming algorithm of planar point circular acoustic array is optimized and simulated.Compared with the conventional beamforming of point circular acoustic array,constant beam width beamforming can reduce the sidelobe of the system and greatly improve the overall performance of the system,which has certain application significance in engineering design.
