Source identification of emitting characters in aircraft cabin

Along with the prolonging of people's staying time in enclosed environments such as spacecraft, aircraft and so on, air pollution in the cabin has become a main factor which endangers occupants' life safety. Therefore, it's crucial to develop investigation about identification of sudden unknown contaminant source location and strength, which could help improve the ability of enclosed environments to deal with sudden contaminant. This paper presented the sensitivity analysis algorithm which can identify source location and strength. Still more, this paper analyzed the identifiable zone of different sensor placements, and provided the better one. The research above can identify the source emitting characters rapidly and accurately, which provides foundation on replying contaminative accidents. Simulation results have proved the virtues of the novel method.
