Study on the Detection Performance of UWB bio-radar with Segmented Time Window

To improve the life detection accuracy of UWB biradar in ruin scene, the paper put forward a layering detection approach based on segmented time window to achieve the goal. Firstly, a bio-radar hardware which can accomplish the layering detection function was implemented. Besides that, to eliminate the influence of individual difference, a frequency and displacement quantitatively adjustable system was established to serve as the standard detection target. Then, free space experiment was conducted to analyze the detection performance of layering detection bio-radar. At last, on-site ruin environment experiment was carried out to verify the detection performance improvement of the layering detection platform. The life-rescuing UWB bio-radar we implemented in the paper is capable of freely choosing the time window to carry out piecewise layering detection. And it is superior to the original detection system in terms of detection accuracy, which can be used for post-disaster relief operations in complex ruin environment.
