This study handles the three-dimensional (3D) angle-only tracking (AOT) problem, which is calculating the target's location and velocity by measuring the target's elevation and azimuth angle. Nowadays, a non-civilian (unmanned) aircraft can accelerate in an unpredictable manner. This study presents a stochastic filter re-start strategy for tracking a target which can abruptly change its velocity in any 3D directions. Moreover, this study assumes that the target's destination information is known a priori. Using the target destination information, the authors can improve the filter accuracy as well as the time efficiency. As far as they know, this study is novel in using the target's destination information for manoeuvring target tracking in 3D AOT problem. The performance of the proposed stochastic filter re-start strategy based on the target's destination information is verified under MATLAB simulations.

过滤器重新启动策略，用于在考虑目标的目的地信息的情况下仅对高机动目标进行仅角度跟踪

这项研究解决了三维（3D）仅角度跟踪（AOT）问题，即通过测量目标的仰角和方位角来计算目标的位置和速度。如今，非民用（无人）飞机会以无法预测的方式加速。这项研究提出了一种用于跟踪目标的随机滤波器重新启动策略，该目标可以在任何3D方向上突然改变其速度。此外，本研究假设目标的目的地信息是先验的。使用目标目的地信息，作者可以提高过滤精度和时间效率。据他们所知，这项研究在利用目标的目的地信息来操纵3D AOT问题中的目标跟踪方面是新颖的。
