摘要

本文主要研究隐藏在墙后的人的生命符号的提取。生命信号提取的主要问题是信杂比较弱。为了提高信杂比，采用了奇异值分解(SVD)方法。利用步进频率连续波(SFCW)雷达系统建立了实验装置，提取被困在胶合板墙后的人的生命信号。在提高信杂比的基础上，利用标准差获得生命信号即呼吸信号的位置，并利用快速傅里叶变换(FFT)成功提取呼吸信号的频率。

Extraction of life sign of human being hidden behind the wall

Extraction of life sign of human being who is hiding behind the wall is addressed in this paper. The major problem in extraction of life sign signal is weak signal to clutter ratio. To improve the signal to clutter ratio, Singular Value Decomposition (SVD) is used. Experimental setup using Stepped-frequency continuous wave (SFCW) radar system is used to extract life sign of human being entrapped behind a plywood wall. After improving signal to clutter ratio, location of life sign signal i.e., breathing signal is obtained using standard deviation and frequency of breathing signal is extracted using Fast Fourier transform (FFT) successfully.
