摘要
采用最小均方(LMS)算法,通过对雷达回波信号进行滤波处理来提取生命参数信号。利用超宽带冲击脉冲雷达对砖墙后的人体进行生命探测,采集雷达回波信号,运用LMS算法对回波进行生命参数信号提取。通过一系列的信号预处理后利用LMS算法可以很好地提取出回波中的生命参数信号。
To extract life- parameter signal by applying LMS algorithm to filter the radar echo signals. Detecting human body behind the brick wall with UWB impact pulse radar, collecting radar echo signals, then extracting life- parameter signal from echo by LMS algorithm. LMS algorithm can extract life- parameter signal in radar echo after a series signal pre- processes.
