Description
Likewise LHC, FCC tunnel should be carefully supervised to ensure safety of personnel. Nevertheless, in case of an accident, in order to increase success of the mission and reduce risks for rescue team, it will be crucial for firefighters to collect as much information as possible about the location of victims inside tunnel before entering the unsafe zone. Due to the large size of FCC, rapid intervention and situation analysis will be even more challenging than in case of LHC. The aim of this study is to develop a reconnaissance system based on ultra-wideband (UWB) impulse radar to detect human presence in harsh environments such as smoke-filled room. A short electromagnetic pulse is sent across the room and reflected signal is sampled with small delays (for distance estimation purpose) using swept-threshold coding and integration. Then, signal processing is carried out to detect micro movements of human body due to lung and heart activity. This presentation introduces the principal outline of the said system and the initial results of the measurement experiment in the real smoke filled room.
