Outline of Final Research Achievements

For the problem of localizing a target in a building, this research proposes a method of using a set of unmanned aerial vehicles (UAVs) flying around the building. In the proposed method, the set of hovering UAVs is first localized by GPS, and then the target is localized using the locations of the UAVs. For time of arrival (TOA)-based localization, a 2-step UAV formation is proposed, which can reduce the localization error. On the other hand, for received signal strength (RSS)-based localization, a method of using a signal attenuation map obtained by compressed sensing-based wireless tomography is proposed. For the TOA-based method, the performance is analyzed by theory and computer simulation, and for the RSS-based method, the performance is analyzed by experiment in an anechoic chamber.
