【 摘 要 】

This study focuses on range estimate for life detection based on the characteristics analysis of life signs by employing the ultra-wideband (UWB) impulse radar. Via analysing the standard deviation of life signs, the time of arrival (TOA) of the pulse from the radar receiver to detection target is estimated based on the calculated energy blocks. Based on the obtained TOA estimates, one area containing life information is determined, which is referred to as region of interest (ROI). Using the signals in ROI, the frequency of human breathing motion is measured more easily and accurately. Different experiments are carried out to test the performance of the new method in through-wall conditions. Results show perfect capability of detection and improving signal-to-noise ratio.
