生命探测仪及其技术原理

Life detector & its technical principle

各种灾害特别是地震灾害严重威胁到灾区人民的生命安全,生命探测仪应用信息检测技术,在灾害区域进行快速生命救援中发挥了极其重要的作用.简要分析音频生命探测仪、红外生命探测仪和雷达生命探测仪的工作原理,给出探测仪系统框图,说明雷达生命探测仪特别是超宽谱雷达生命探测仪,以其特有的多种优势成为最具应用潜力的生命探测仪器.

Various disasters especially earthquake are a grievous threat to people＇ s lives in disaster areas. Using detection technologies, life detector played a vital role in quick life rescue. This paper is aim to analyze the working principle of audio life detector, Infrared life detector and radar life detector. It shows a system block diagram of the three life UWB radar life detector has the most potential detectors. It also shows that radar life detector especially applications with its advantages.
