| Abstract: | For the improvement of the audio directional system, this paper designs a set of beamforming system, and proposes the basic principle, control plan .software and hardware design; In this system, with Xilinx XC3S1400A as a central control chip, with the parametric acoustic array and ultrasonic phased algorithm combined together as control strategies; The experimental results show the system can control the direction of beam deflection. It can be used to complete beamforming. |
