Abstract When fusing the decisions of local sensors transmitted via Nakagami fading channel, the Likelihood ratio test based on channel statistics (LRT-CS) proposed in the literature requires the detection probability of local sensors and involves an infinity series. However, the detection probability of local sensors generally is a priori unknown for an uncooperative target. Thus, a Censoring based Mixed Fusion (CMF) is proposed, which is simple and does not need the detection probability of local sensors. Monte Carlo simulations show that the CMF has small performance degradation in comparison with the LRT-CS for unknown detection probabilities of local sensors. Therefore, CMF can substitute LRT-CS in practice.
