摘要: 针对雷达组网数据融合系统,对其系统性能进行了详细分析。介绍了2种典型雷达组网模式(集中式融合和分布式融合)的工作原理,对其抗干扰、反隐身、融合精度、融合识别和通信量等方面的性能进行了定量研究。研究表明,集中式雷达组网的实质是多雷达探测信息的“并”,利用信息互补,具备航迹合成功效;分布式雷达组网的实质是多雷达探测信息的“交”,利用信息冗余,具备电假目标航迹鉴别功效。研究结果可为新一代智能雷达组网数据融合系统的建设提供一定的参考意义。

Abstract: The performance analysis of netted radar data fusion systems was proposed. The principles of two representative radar netting modes (i.e., centralized fusion and distributed fusion) were introduced and the associated capabilities of anti-jamming, anti-stealth, fusion accuracy, fusion discrimination, and communication requirements were quantitatively analyzed. Simulation results indicate that the netting essence is, centralized fusion by using ‘or' rule to complement information and realize trajectory composition whereas distributed fusion by using ‘and' rule to reduce information redundancy and realize discrimination ability. The research can provide some enlightenment for the newly-developed intellective netted radar data fusion systems.

Key words: radar netting, data fusion, centralized fusion, distributed fusion, performance analysis, system simulation
