摘要

摘要: 由于临近多静止人体目标之间存在较强的相互干扰，仅利用单通道生物雷达的距离像难以区分多个静止人体目标。为解决上述问题，该文利用超宽带多输入多输出（UWB MIMO）生物雷达获取多静止人体目标的2维高分辨图像，从空间上更好地分隔多静止人体目标，然后基于UWB MIMO图像的慢时间序列对人体生理信号进行增强，有效抑制人体目标间的相互干扰。实测数据结果证明该文所提方法能够获得相互靠近的多静止人体目标的高分辨图像，使后续的多静止人体目标高性能检测与定位成为可能。

Abstract: Because of the mutual interference between multiple stationary humans, distinguishing individuals via the range profile of a single-channel bioradar is difficult. To solve this problem, we used an Ultra-WideBand Multiple-Input Multiple-Output (UWB MIMO) bioradar to compose high-resolution two-dimensional images. These images allow multiple stationary humans to be separated from space. Then, vital signs are enhanced on the basis of the UWB MIMO image sequence, thereby leading to effective suppression of interference. The experimental results demonstrate that the proposed method can compose high-resolution images of multiple stationary humans. Thus, high-performance detection and localization of multiple stationary humans can be expected.
