“低慢小”无人机探测方法

Detection Methods for Low-Slow-Small (LSS) UAV

"低慢小"无人机在航拍、农业、娱乐、军事等领域的广泛应用,在带来产业升级的同时,也带来了安全隐患。作为对"低慢小"无人机管控与反制的前提,"低慢小"无人机探测成为一个备受关注的研究课题。从"低慢小"无人机与客机、战斗机等传统探测目标特性上的不同出发,分析"低慢小"无人机探测的难点,梳理当下针对这一问题研究的最新成果,总结雷达探测、激光探测、光电探测、声探测、金属探测、无线电探测等方法,比较各原理之间的性能差异,提出移动探测、融合探测、跟踪探测等发展方向。

Low altitude, slow speed, and small size unmanned aerial vehicle(LSS UAV) has been widely used in photography, agriculture, security guard, military, etc. Though the UAV industry brings revolutionary progress in these domains, it causes a severe threat both to the civilian and military. The detection for LSS UAV is an important problem because it is the precondition of countering, and the contrasts of detectable signals between LSS UAV and traditional targets are beyond the ability of the current detection devices. Firstly, this paper analyses the difficulties of LSS UAV detection. Secondly, this paper surveys the latest achievements in this subject, including radar detection, laser detection, electric-optical detection, acoustic detection, metal detection, radio frequency detection. Finally, this paper proposes that the directions of future development could be mobile detection, multi-sensors detection, and tracking before detection.
