基于自适应有源辅助的纯方位无源跟踪方法

摘要

For the active detection was liable to be interfered,the passive tracking precision was low and filte-ring was divergent,this paper put forward the passive tracking method with adaptive active assistance.This method combined the advantages of two kinds of tracking method.During the passive tracking process,accord-ing to whether the quality met the requirement of task model,the active detection equipment adaptively assisted passive detection equipment to detect and track the target,which would revise the tracking errors and inhibit the divergence of filtering,and realize the complementary advantages.Simulation and analysis showed that the method not only could effectively ensure the quality of tracking,but also could control the electromagnetic radia-tion,ensured the concealment and accuracy of the tracking.%针对有源探测易受干扰、无源探测存在跟踪精度低和滤波发散的问题，提出了基于自适应有源辅助的纯方位无源跟踪方法。该协同探测方法综合了两种跟踪模式的优点，即在纯方位无源跟踪目标期间，依据跟踪质量是否满足任务模式要求，有源探测设备自适应的实施辅助探测跟踪，以此修正跟踪误差并抑制滤波发散，实现了优势互补。仿真分析表明，该协同方法不仅能保证较好的跟踪质量并能有效地控制有源设备的电磁辐射，保证了跟踪的隐蔽性与精确性。
