摘　　要：设计一种用于雷达波生命探测仪的信号处理系统。该系统主要由TI公司高性能浮点DSP芯片TMS320C6711B和AD公司16位A/D转换芯片AD7707构成,具有体积小、功耗低、性能强、处理快、实时多窗口显示等优点。给出了系统的硬件电路构成和软件设计,并介绍了生命参数信号的采集处理流程及人体状态、数量等识别显示的综合算法流程。A kind of signal processing system used in radar life-detector is designed. This system is mainly composed of MS320C6711B（a kind of high performance float DSP chip made by TI Company） and AD7707（ a kind of 16-bit A/D convert chips made by AD Company）. It has many advantages such as small volume, low power consumption, high performance, fast speed, real-time multiple-window display and so on. The hardware design and software flow are both given, and the whole al- gorithm flow is discussed which mainly includes the life-signal sampling and processing, the recognition of the human body parameters and so on.
