由于航空目标相对地面目标具有更快的运动速度、更广的运动范围,对航空目标的三维精确定位极具挑战性.本文提出了一种多传感器组网的航空目标三维定位算法,以两个高空无人飞艇各载一部光学传感器设备,无人机-艇载双基地两坐标雷达,多平台协同实现对航空目标的精确定位为研究背景,解决了由于各传感器量测维度欠完备、无法独立获得目标三维空间精确位置,导致传统点迹关联、目标定位方法失效等问题.首先,在空间对准的基础上提出了基于角度-距离两级点迹关联算法,实现多传感器缺维量测的有效关联;其次,通过目标引导点构建、椭球空间Nelder-Mead欧氏距离寻优、方位面空间投影,在各空间量测模型上确定目标初始定位点;最后,通过无迹变换和同源数据压缩得到目标精确定位点.仿真结果表明,该算法实现了缺维情况下雷达-双光学量测数据的稳定关联,且对航空目标的最优定位误差可达到115.7 m.
Accurately locating aviation targets in three dimensions presents formidable challenges owing to their high-speed movements and expansive maneuverability compared to ground targets. This paper presents a three-dimensional positioning algorithm for aerial targets based on a multi-sensor network. Using two high-altitude unmanned airships
each equipped with an optical sensor device
and UAV-shipborne bistatic dual-coordinate radars
the study focuses on achieving precise positioning of aerial targets through multi-platform collaboration. This approach addresses the limitations of traditional methods
which often fail due to the incomplete measurement dimensions of individual sensors
preventing accurate independent determination of the target’s 3D spatial position. Our approach begins with the introduction of a two-level point-trace correlation algorithm grounded in spatial alignment
leveraging both angle and distance to effectively correlate non-dimensional measurements from multiple sensors. Subsequently
we establish the initial positioning points of the target on each spatial measurement model through the construction of target guidance points
employing techniques such as ellipsoidal space Nelder-Mead Euclidean distance optimization and azimuth space projection. Finally
precise positioning points of the target are obtained through the utilization of unscented transform and homologous data compression.Simulation results demonstrate the efficacy of our algorithm in achieving stable correlation of radar-dual optical measurement data
even in scenarios where dimensionality is lacking. Notably
our algorithm achieves an optimal positioning error for aviation targets as low as 115.7 meters.
