摘　　要：针对本地检测器的检测环境比较恶劣和本地检测器至融合中心的传输信道为非理想信道的情况,提出一新的反馈算法。将融合中心的判决信息反馈至融合中心,用来剔除工作不正常的本地检测器或性能恶劣的信道,基于性能正常的本地判决信息,应用聂曼-皮尔逊(NP)规则来推出融合中心的最优化判决形式。最后通过三检测器的系统仿真表明:在此情况下,融合中心应用反馈使检测性能得到了改善。Aiming at the condition of atrocious detection environment of local detectors and non-ideal channels of local detectors to fusion center, a new feedback arithmetic is put forward in this paper. The decision of fusion center is feed back to fusion center to eliminate the local detectors not in order or channel of atrocious performance. Based on the local decisions in order, according to Neyman-Pearson（NP） rule, the optimizing decision of fusion center is designed. At last, the simulation of three detectors shows that using feedback improves the detection performance in this condition.
