【Abstract】 This paper considers distributed detection systems with serial topological structures. The detection system consists of N sensors and the system performance is optimized using Neyman Pearson criterion. In order to optimize the system performance, the optimal sensor decision rules must be designed jointly. The necessary conditions for optimum detection for the distributed detection systems are derived, and a numerical iterative algorithm for obtaining the optimum sensor decision rules is presented. Using this detection fusion algorithm to optimize the performance of a distributed underwater signal detection system, the system performance can be improved significantly.更多还原
