在紧急情况下，如地震，受害者往往被困在倒塌的战壕或建筑物中。如果第一响应者配备具有穿墙能力的超宽带（UWB）雷达传感器，搜索和救援将大大简化。出于这一挑战，我们研究了基于超宽带雷达传感器的穿墙人体检测。我们观察到，基于离散傅里叶变换（DFT）的方法不能很好地工作在信号衰减高的场景中，并且基于DFT的方法具有高计算负载，这使得它难以在真实的世界中使用。提出了一种基于标准差的穿墙和木门人体检测方法，并对检测阈值的选取进行了分析。我们的方法是非常简单的实现，但它具有很高的精度。在适当的检测门限下，可以实现完美的检测（无检测错误）。(C)2015 Elsevier B.V.版权所有。
In an emergency scenario, such as earthquake, victims can often be trapped in collapsed trenches or buildings. Search and rescue would be greatly simplified if first responders were equipped with a UltraWide Band (UWB) Radar sensor which has sense-through wall capability. Motivated by this challenge, we study sense-through-wall human detection based on UWB radar sensors. We observed that a Discrete Fourier Transform (DFT)-based approach could not work well in scenarios where signal attenuation is high, and the DFT-based approach has high computational load, which makes it difficult to be used in real world. We propose a standard deviation (std)-based approach to sense-through wall and sense-through wooden door human detection, and make analysis on detection threshold selection. Our approach is very simple to be implemented, but it has high accuracy. It can achieve perfect detection (no detection error) with appropriate detection threshold. (C) 2015 Elsevier B.V.
