| Abstract: | The method of theoretical analysis of the coordinated relationships between the fusion rule and local decision rules of the distributed detection systems with multiple sensors is proposed in the sense of Neyman Pearson criteria. The selection of decision rules of two suboptimal systems and the globally optimal system are fully given, on the basis of which the above three systems are compared in performance and simulated in Rayleigh noise by a computer. The results show that the detection performance and ROC of the globally optimal system are the best in the distributed detection. It follows that the method is correct and valid. |
