人体呼吸非接触测量中IR-UWB雷达关键参数的研究
Study on the Key Parameters of Remote Respiration Measurementvia IR-UWB Radar
摘要
Abstract
The equivalent-time sampling interval is one of the most important parameters for the impulse-radio ultra-wideband (IR-UWB) radar that concerns the remote measurement of respiration, which was theoretically and experimentally investigated in this paper for the ifrst time. According to the measurement results, the interval had to be smaller than half of the thorax displacement due to the respiration. Therefore, it should be as small as possible for improving the respiration measurement capability of the IR-UWB radar. The equivalent-time sampling period of IR-UWB radar was also determined by the equivalent-time sampling interval. Reduction of the equivalent-time sampling period had no obvious inlfuence on the improvement of the respiration measurement capability. The study in this paper presents significance for the design of the IR-UWB radar in the application of remote vital sign measurement.关键词
