摘要

摘要: 超宽带（UWB）雷达探测技术可实现面向钻孔救援的矿井人体目标探测，但UWB电磁波易受灾变矿井复杂环境影响，UWB雷达回波信号易受到灾变矿井背景杂波、环境噪声影响，导致难以实现灾变矿井人体目标精准探测。针对上述问题，介绍了基于UWB雷达的井下目标探测场景及人体目标探测原理，分析了UWB电磁波特性研究现状和UWB回波噪声滤除方法研究现状。总结了存在的问题：① UWB电磁波在灾变矿井复杂环境中的传播特性需深入研究。② 背景杂波产生原因尚未明晰，灾变矿井背景杂波与环境噪声滤除技术研究较少。③ 面向钻孔救援的UWB雷达人体目标探测技术仍需改进。针对现有技术的不足，展望了面向钻孔救援的UWB雷达井下人体目标探测技术的发展趋势：① 深入研究UWB电磁波穿透传输关键表征参数对井下复杂环境特征的敏感程度。② 构建适用于灾变矿井的背景杂波与环境噪声滤除方法。③ 深入优化面向钻孔救援的UWB雷达人体目标探测技术。

Abstract: The ultra wideband (UWB) radar detection technology can achieve mine human target detection for drilling rescue. However, UWB electromagnetic waves are susceptible to the complex environment of catastrophic mines. The UWB radar echo signals are susceptible to the background clutter and environmental noise of catastrophic mines. It is difficult to achieve precise detection of human targets in catastrophic mines. In order to solve the above problems, the underground target detection scenarios and human target detection principles based on UWB radar are introduced. The research status of UWB electromagnetic wave characteristics and UWB echo noise filtering methods are analyzed. The existing problems are summarized as following points. ① The propagation characteristics of UWB electromagnetic waves in the complex environment of catastrophic mines require in-depth research. ② The reason for the generation of background clutter is not yet clear. There is limited research on the filtering technology of background clutter and environmental noise in catastrophic mines. ③ The UWB radar human target detection technology for drilling rescue still needs to be improved. In response to the shortcomings of existing technologies, the development trend of UWB radar underground human target detection technology for drilling rescue is prospected. ① It is suggested to do in-depth research on the sensitivity of key characterization parameters of UWB electromagnetic wave penetration transmission to complex underground environmental characteristics. ② It is suggested to construct methods for filtering background clutter and environmental noise suitable for catastrophic mines. ③ It is suggested to deeply optimize UWB radar human target detection technology for drilling rescue.
