This proposal focuses on the TOA signal propagation modeling and key algorithms for the positioning of fire emergency responders in complicated architectural environment. In the aspect of TOA signal propagation modeling, we take in-depth analysis of the differences between the positioning of fire emergency and traditional positioning applications, in view of antenna configuration, human body gesture, etc. A signal propagation model for TOA based firefighter localization system in complicated architectural environment will be established based on measurement and statistics. In the aspect of key algorithms, as TOA signals are greatly influenced by different scenarios, TOA ranging and direction detecting algorithm are proposed based on precise Direct Path (DP) estimation method. Then, mobile station localization and multi-bjective collaborative localization algorithms are put forward to meet the need of relative positioning requirements in fire emergency applications. As a practical application of the model and algorithms, a firefighter localization system will be designed and implemented to validate the values of the research results.
