| Abstract: | 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. |
