摘　　要：介绍了一种以双核处理器芯片TMS320C6657为核心处理器的被动声探测系统,利用24位同步ADC、FPGA和MCU实现数据采集、信号处理和人机交互的功能。详细阐述了基于双核DSP技术的声学目标定向识别软件设计。实测结果表明,该探测系统较已有探测系统的性能有了明显提高。This paper introduces a passive sound detection system based on TMS320C6657, a dual-core DSP. The 24-bit simultaneous sampling ADC, FPGA and MCU are used to realize data acquisition, signal processing and human-computer interaction. The design of acoustic target orientation and identification software based on dual-core DSP is described in detail. The measured results show that this detection system has improved the performance of the existing system.
