针对矿山灾害事故造成逃生通道被堵，被困人员位置难以确定的难题；依据超宽带(UWB）雷达生命信息探测和位置探测原理和特点，结合现有超宽带雷达探测技术，提出了适用于钻孔探测的UWB雷达架构，明确了关键技术参数，研制了UWB雷达生命信息探测仪；开展了不同探测距离、位置、目标数量和微弱体动下UWB雷达探测试验，获得了3种条件下的探测图谱特征。试验结果表明：UWB雷达生命信息探测仪穿透0.5 m砖墙，在灾害变形后的复杂地貌下可精确定位人员空间信息，较好地从雷达回波观测出4.0 m范围内的人员小范围移动；当多个人体目标在雷达收发天线同一范围内，且距雷达径向相对位置有差异时，可根据回波图谱判断出人体目标数量。

In response to the problem of blocked escape routes and difficulty in determining the location of trapped personnel caused by mining disasters and accidents, based on the principles and characteristics of ultra wideband (UWB) radar life information detection and position detection, combined with existing UWB radar detection technology, a UWB radar architecture suitable for borehole detection is proposed, key technical parameters are clarified, and a UWB radar life information detector is developed; we conducted UWB radar detection experiments under different detection distances, positions, target numbers, and weak body movements, and obtained detection spectrum features under three conditions. The experimental results show that the UWB radar life information detector can penetrate a 0.5 m brick wall and accurately locate personnel spatial information in complex terrain after disaster deformation. It can observe small-scale movements of personnel within a range of 4.0 m from radar echoes; when multiple human targets are within the same range of the radar transmitting and receiving antennas, and there are differences in their radial relative positions from the radar, the number of human targets can be determined based on the echo spectrum.
