高压阻尼线 Abstract：A sound source location system based on FPGA is studied and implemented. Acoustic signals are collected by several microphone arrays and transmitted to the main controller by A/D module. Using GCC，PATH weighting and SCOT weighting，the time difference is obtained，the coordinate system is established，and the coordinate is located by calculating. The location technology based on microphone array has good security and concealment，农产品干燥机and has a good prospect in military field. Several weighted positioning effects are simulated and analyzed by MATLAB，and the optimal scheme of positioning algorithm based on FPGA is determined by experiments.
