Summary:针对小体积声探测系统对阵元数量的要求，设计了基于FPGA的双声传感器定位系统。该定位系统利用两个声传感器接收的回波的声压和时延值进行联合定位，可以达到减小阵元数量的目的。同时，利用硬件描述语言和DSPBuilder完成了整个系统的构建。仿真和实验结果表明，所设计的定位系统工作频率可以达到94．4MHz，完成一次定位只需要52μs，定位误差在1％之内。
Bibliography:Aiming at the demand on the number of array elements by acoustic detection system, the location system of double acoustic sensors based on FPGA was designed. The location system utilized the sound pressure and time delay value of echo received by double acoustic sensors to joint position, that achieved the purpose of reducing the number of array elements. Meanwhile, the system was designed by hardware description language and DSP Builder. The simulation and the experiment indicate that the location system operating frequency can reach 94.4 MHz, and it only requires 52 Ixs to complete a positioning with error less than 1%.
