研究采用串行系统配置结构的分布式检测融合系统。融合系统由 N部传感器构成。由于融合系统的检测性能由 N部传感器的判决规则共同决定 ,故为了使系统性能达到最优 ,需要联合设计各部传感器的最优判决规则。文中给出了融合系统检测性能最优化的必要条件 ,以及求解最优系统判决规则的数值迭代算法。采用该融合算法对分布式水声信号检测系统的性能进行优化 ,系统性能有明显提高
The distributed detection fusion system based on serial system configuration is studied. The fusion system consists of N sensors. Since the detection performance of the fusion system is determined by the decision rules of N sensors, in order to achieve optimal system performance, the optimal decision rules of the sensors of all the departments need to be jointly designed. In this paper, the necessary conditions for the optimization of fusion system performance are given, and the numerical iteration algorithm for solving the optimal system decision rules is given. The fusion algorithm is used to optimize the performance of distributed underwater acoustic signal detection system and the system performance is obviously improved
