摘　　要：针对有源探测易被截获发现,无源侦察精度较低问题,研究采用多机有源无源协同工作方式降低被发现概率,提高探测精度。在探测初始阶段,先利用多机时差算法对目标进行粗定位。在探测跟踪阶段,再使用无源粗定位结果牵引有源探测平台实施目标快速精定位,提高定位精度。仿真结果表明,文中所设计的多机有源无源协同探测方式,对目标定位精度优于单纯的多机无源定位和有源探测方式,且具有作用距离远和良好的隐蔽性优点。In order to solve the problem that the active detection is easily intercepted and the passive reconnaissance accuracy is low,multiple aircrafts active cooperate with passive has been researched to reduce the probability of discovery and improve the detection accuracy.Multiple aircrafts time difference algorithm is uses to coarsely locate the target in the initial stage of detection.The passive coarse positioning result is used to pull the active implementation of the single-station target for rapid fine positioning to improve the positioning accuracy in the stage of detection and tracking.The experimental results show that the target positioning designed in this paper by accuracy the multiple aircrafts active cooperate with passive detection method is better than the method which implement by the single multiple aircrafts passive location and active detection,and has the advantages of long range and good concealment.
