| 摘 要： | 基于步进频连续波,利用MTD滤波,通过时域、频域联合检测,研究了生命迹象探测的新方法,在检测到人体的同时,实现测距的目的。首先,基于人体微动模型建立步进频连续波生命迹象探测的回波模型;然后由回波得到距离像信息,划分距离门,经时域检测后,对有信号的距离门内距离峰值变化信息进行傅里叶变换;再通过MTD滤波,滤除静止目标的影响,经频域检测,即可检测到人体。仿真证明了该方法的有效性。

| Abstract: | Based on stepped-frequency continuous wave(SFCW) and MTD filter with joint detection in time and frequency domain,a new method for life detection is proposed to get the range information in detecting human beings.Firstly,stepped-frequency continuous echo model in life detection built is according to human vibration model.Secondly,range gate is divided and time domain detection is used to gain the actually range gate where the targets are.And thirdly,the frequency information of these range gates is obtained... |
