中文摘要	为提高基于二元局部判决的分布式广义符号检测器的检测性能,研究了基于广义符号统计量的分布式检测,提出了直接求和与删除求和两种融合准则。在W e ibu ll杂波和Sw erlingII目标下,直接求和融合具有比某参数化的分布式恒虚警检测更好的检测性能,并能达到集中式广义符号检测相同的性能。某些传感器信杂比极低时,采用删除求和融合能获得比直接求和融合更好的检测性能。给出了在多雷达分布式检测中应用各种融合准则的方法。; Two types of local generalized sign statistics-based distributed detection fusion schemes,direct summation and censored summation,are presented to improve the detection power of binary local decision-based distributed generalized sign detection in multiradar distributed detection systems.Numerical tests indicate that the direct summation fusion rule provides better performance than the binary local decision-based rule or previous parametric distributed CFAR schemes with Weibull clutter.The direct summation fusion scheme has the same detection power as the centralized generalized sign detector.If some sensors' signal-to-clutter ratios are very low,the censored summation fusion has better performance than direct summation. Applications in multiradar distributed detection are also presented.; 全国博士学位论文作者专项资金资助项目(200237)
