摘要
为了提高雷达生命信号检测的准确性,文章提出基于算法的雷达生命信号检测方法。首先雷达发射调频连续波,回波信号中包含人体生命体征信息,经过一系列信号预处理后,得到含有生命体征信息的相位数据,最后通过算法将生命体征信息准确地提取出来,并且实现对人体生命信号的非接触式检测。
In order to improve the accuracy of FMCW radar life signal detection,this paper proposes a radar life signal detection method based on IAA algorithm.Firstly,the radar transmits frequency modulated continuous wave,and the echo signal contains human vital signs information.After a series of signal preprocessing,the phase data containing vital signs information is obtained.Finally,the vital signs information is accurately extracted through the algorithm,and the non-contact detection of human vital signals is realized.
