摘　　要：为了提升地空导弹武器系统体系抗干扰及隐蔽性作战能力,结合新装备主动雷达和基于时差法测量的被动雷达系统各自技术优势,提出了一种主动雷达辅助的被动雷达协同探测跟踪模式,并针对该模式研究设计了一种协同探测跟踪算法。通过引入模糊推理函数,利用新息方差实际值和量测误差协方差变化率值作为模糊输入控制量,实时控制主动雷达的开关机工作,不仅实现了对主动雷达的精确化和实时化控制,而且提高了系统跟踪精度。通过Monte Carlo仿真,进一步验证了协同模式的合理性以及改进算法的有效性和正确性。To improve the anti-interference and stealth capability of surface-to-air missile system,a synergistic operating mode,i.e.,the passive radar tracking system with assistance of active radar,was proposed based on the advantages of both the active and passive radars .A new cooperated detecting and tracking algorithm was designed based on the mode .The operation of the active radar was controlled in real time by introducing the fuzzy reasoning function and using the new practical variance and the change rate of measure error variance as input control variables .This method could not only control the active radar precisely and in real time,but also improve the system tracking precision .Monte Carlo simulation demonstrates the rationality of the synergistic operation model and the availability and correctness of the improved algorithm .
