Abstract
In this work, a wind speed measurement model based on fuzzy data fusion of the time-of-flight (ToF) information is presented. This information is obtained through threshold detection (TH) and phase difference (PD) techniques. Fuzzy membership functions are derived from ToF measurement values and represent measured values and their uncertainties. Two data fusion methods are presented based on the compatibility relationship between elements to be combined and using weights defined by the OWA (Order Weighted Average) operator. Uncertainty analysis the TH and PD techniques is carried out by determining the uncertainty associated to the ToF measurement. ToF data fusion values are determined considering several measured values using the TH and PD techniques. ©2008 IEEE.
