三维机动辐射源的单站无源跟踪方法

针对单站无源定位中对于机动辐射源利用角度及其变化率能否定位的问题，引入雷达对机动目标跟踪的多级噪声自适应(ANL)法和交互多模(IMM)方法，以及机动目标运动模型如Singer模型、匀加速模型等，研究并提出了两种对机动辐射源利用角度及其变化率进行单站无源跟踪方法。通过计算机数字仿真表明，在满足定位可观测条件的前提下，对机动辐射源仅仅利用角度及其变化率是可以定位的，其中IMM方法具有比较优秀的性能。

Tracking Algorithm of 3-D Maneuvering Emitter with a Passive Single Observing Station

To investigate the problem of whether a single p assive observer can locate maneuvering emitter through its bearings and bearing s changing rates. We introduce algorithms of maneuvering target tracking by rada r named adjustable noise level (ANL) method, interacting multip model(IMM) metho d and by introducing maneuvering target model such as singer model, Constant Acc eleration(CA) model, two algorithms of single observer passive tracking maneuver ing emitter using bearings and its changing rates were studied. Computer simulat ion results show that under the condition of observable location, we could use b earings and its changing rates information to locate maneuvering emitter, and IM M method has excellent performance for tracking a maneuvering target.
