Through-the-wall human respiration detection using impulse ultra-wide-band radar

This paper addresses an ab-initio research of the human respiratory detection behind the reinforced concrete wall using the ultra-wide-band (UWB) radar, which can be used for battle field and victim search applications. The customized signal processing algorithms is applied and the impulse ultra-wide-band (UWB) radar system is employed to detect human respiration from different distances. The results show the accuracy and robustness of our system in through the reinforced concrete wall respiration detection from 0.7 m to 2.5 m.
