摘　　要：单站条件下,高速网络和高性能服务器的应用克服了传统多雷达组网时通信带宽和融合中心计算性能的约束,使集中式检测成为可能。论文基于传统检测理论,推导了贝叶斯准则下集中式检测与分布式检测的实现原理、阈值设计等内容,从算法理论上论证了集中式检测的优越性。进一步研究了集中式检测在工程实践中需克服的关键技术问题。为多雷达联合检测技术提供新的研究思路。The centralized detection is possible in the single station with the application of the high speed network and the high performance server ,which get rid of the constraints of the communication band and the processing performance of fusion center during the construction of the radar network .The basic theory ,the threshold set and et al of the centralized de‐tection are deducted based on the Bayes rule ,compared with that of the distributed detection ,which proves the advantages of the centralized detection in theory .Further ,the key technology of the centralized detection in engineering practice is studied . The conclusion in the paper provides the new approach for the joint detection of the multiple radars .
