A Novel Performance Evaluation Method of Ultra-Wideband Positioning System Based on Fuzzy Comprehensive Evaluation

This paper mainly concerns the problem of performance evaluation for an Ultra-Wideband (UWB) positioning system. An evaluation index system suitable for UWB positioning system is established to assess the performance of UWB positioning system from multiple aspects, including accuracy, reliability and anti-interference ability. Analytic hierarchy process (AHP) and entropy weight method (EWM) are combined to yield a more objective weight for each evaluation index. Besides, fuzzy comprehensive evaluation (FCE) is used to conclude the evaluation result. An illustrative example is provided to demonstrate the effectiveness of proposed evaluation index system and evaluation method.
