| 摘 要： | 贝叶斯检测融合策略是一种比较传统的分布式检测融合方法,必须给定待检测现象的先验概率和各局部传感器的虚警概率和漏检概率,而在现实应用中,统计量是未知的或者是随时间变化的.因此,研究了一种纽曼一皮尔逊准则下的门限自适应分布式检测系统的融合算法.算法可根据观测数据,自动在线调整门限,使得局部传感器检测达到最佳,从而提高系统的检测性能.计算机仿真的结果表明,算法能较快地收敛,相对局部传感器,融合中心的检测性能也明显地有了提高.

| Abstract: | The detection fusion under Bayes criterion is a traditional method of distributed detection fusion.The prior probability of the unknown phenomenon,the false alarm probability and the miss probability of the local sensors should be given in the above-mentioned method,but these statistics are unknown or variable in the practical applications.Therefore,a distributed detection fusion algorithm based on adaptive threshold is studied under the Neyman-Pearson criterion.The algorithm can adjust the threshold of the... |
