In this paper, we analyze the distributed FGO-CFAR detector in homogeneous and Non-Homogeneous Weibull clutter with an assumption of known shape parameter. The non-homogeneity is modeled by the presence of a clutter edge in the reference window. We derive membership function which maps the observations to the false alarm space and compute the threshold at the data fusion center. Applying the ‘Maximum’, ‘Minimum’, ‘Algebraic Sum’ and ‘Algebraic Product’ fuzzy rules for L detectors considered at the data fusion center, the obtained results showed that the best performance is obtained by the ‘Algebraic Product’ fuzzy rule followed by the ‘Minimum’ one and in these two cases the probability of detection increases significantly with the number of detectors.
