摘要：为解决目前现有的接收机系统研判信号可靠性低、误判率高、稳定性差等缺点，研制了以数字信号处理技术为核心的清管器接收机系统。系统设计以微弱信号进行相敏检波处理为重点，模拟信号数字化为关键，用单片机完成测量运算与控制功能。经过分析和设计，该系统产品具有使清管器数据处理的能力更强，处理的结果更可靠，准确率更高，大大减少了对错误信号的误报情况，具有广阔的应用前景。

Abstract：In order to solve the current drawbacks of receiver system such as the fewer reliability and the high erroneous judgment, the paper will focusing on developing the pig receiver based on digital signal processing technology. The system design makes the point on the weak signal processing phase sensitive detector and analog signal digital. It also used SCM to complete the measurement operation and control function. After the analysis and design, the system will be more stronger to deal with data, more reliable and accurate greatly reducing wrong reportment of error signal, and has broad application prospects.
