摘　　要：针对多传感器协同跟踪中无源传感器对雷达的目标指示问题进行了深入分析,重点研究了目标的指示交接需求及其触发机制。分析了协同跟踪中的目标指示交接需求,同时依据无源与有源传感器协同特性建立顺序处理结构的多传感器融合跟踪模型。在此基础上,采用协方差控制思想设定无源传感器对雷达的目标指示触发准则。通过仿真对触发准则进行了验证,并讨论了目标指示触发时机的影响因素,确保传感器间的目标指示能够自发进行。Issue of target instruction of passive sensors on radar in multi-sensors cooperative tracking is analyzed,the cueing and handoff demand and triggering mechanisms are researched. Analyze cueing and handoff demand and set up multi-sensor fusion tracking model under sequential processing structure,according to the synergistic characteristics of passive and active sensors. Then covariance control idea is adopted to form the triggering criterions between the passive sensors and radar. Simulation verifies criterions and discusses the influential factor of triggering time in cueing and handoff to assure target instruction can be carried out spontaneously between sensors.
