摘　　要：针对多传感器分布式检测信息融合系统 ,研究了在N P检验准则下的融合算法。该算法在局部检测时使用了似然比检验 ,而在融合中心则使用了N P检验。针对典型瑞利分布环境给出了融合中心采用AND、OR和K/N三种融合规则时 ,检测门限、检测概率Pd、虚警概率Pf 和信噪比之间的对应关系。仿真结果验证了算法的有效性 ,并证实了三种融合规则均可提高全局检测性能。Towards the distributed multiple sensor detection information fusion, detection performance under N P criterion is studied, while the algorithm for local detection is based on likelihood criterion. A method of performance analysis under three kinds of fusion rules, which are AND OR K/N rules, is proposed with Rayleigh distribution environment. Computer simulations are presented to show the relationships of detection threshold, probability of detection P d, probability of false alarm P f and the signal-to-noise ratio and to confirm the validity of the algorithm.
