【摘要】 为了有效降低波束形成声源定位中的空间混淆现象,改善声源定位波束图,在常规阵列基础上提出一种旋转阵列布局方法。以十字阵列为模型,采用去自谱的波束形成方法对多声源定位的仿真结果表明,旋转阵列可以有效抑制空间混淆误差,并获得较高的处理增益,准确的定位声源。更多还原

【Abstract】 In order to reduce the aliasing errors of the sound source localization by beamforming technology,a rotating array was proposed based on traditional array.Auto-spectrum removal beamforming technology was applied to simulate the multi-source localization because of its satisfactory anti-interference performance.Simulation results show that the rotating array can suppress the spatial aliasing errors effectively,and obtain a higher processing gain.更多还原
