摘要

数字波束形成(DBF)可以描述为每个天线单元接收到的数据的加权和。它本质上是一种空间滤波器，已广泛应用于多目标呼吸检测。然而，这种解决方案仅限于角分辨率。本文提出了一种不受角分辨率约束的差分波束形成方法，用于分离距离较近的多个目标的呼吸信号。实验结果表明，该算法具有良好的性能。

Noncontact Respiration Detection of Multiple Closely Positioned Subjects with Difference Beamforming

Digital beamforming (DBF) can be described as the weighted summation of the data received by each antenna unit. It is essentially a spatial filter that has been widely used in multi-target respiration detection. However, this solution is limited to angular resolution. In this paper, a difference beamforming has been proposed to separate the respiration of multiple closely positioned subjects without being constrained by angular resolution. The experimental result shows the superior performance of the proposed algorithm.
