Research on similarity metric distance algorithm for indoor and outdoor firefighting personnel precision wireless location system based on vague set on UWB

Based on the UWB indoor scale precision firefighter wireless positioning system, the similarity metric distance algorithm based on intuitionistic fuzzy Vague sets is constructed, and a new distance formula is constructed. Combined with the time difference of arrival (TDOA) algorithm, it is helpful to improve the accuracy of the tag location algorithm Degree, to achieve an effective technological breakthrough.
