Design of two flare UWB antenna dedicated to the research of alive buried victims

This document presents the antenna design for the detection of alive victims buried under thick layers of rubble. The antenna is used with UWB Radar techniques in order to locate buried alive victims. The detection is based on the signature of alive persons by using Doppler analysis of movements and respiration. Detecting victims in this environment is very difficult due to the large dynamic range of signal levels. In fact, the reflected signal caused by the buried alive victim is very low behind other reflected or disturbing signals such as mobile phones, vegetation movements, water, rescuers... A two flares UWB antenna, light weight and easy transportable has been specially design for the research of buried victims beneath building rubble. This paper focuses on antenna design, simulation and measurement. These measurements have been made by IETR and CEA. The experimental results show a good comparison between measurements and simulations.
