Real Time Counter-UAV System for Long Distance Small Drones using Double Pan-Tilt Scan Laser Radar

摘要

The ground based electro-optical tracking system (EOTS) and electro-optics and infrared (EO/IR) are the mostpopular small UAV (C-sUAV) detection systems. The EO/IR systems are able to detect sUAVs at a longdistance about several kilometers under clean environment. However, its performance is degraded in variousnoises like fixed patterns, dead/bad pixels and complex background conditions such as saturated images or foggyenvironments. In this study, we propose an efficient methodology using high power laser radar for real time CsUAVsystems. The goal of our system is to find a 0.5 meter sUAV at 2 kilo meter distance in real time. For thatchallenging goal, we use a laser radar with dual pan-tilt scanning systems and also apply the variable-radiallybounded nearest neighbor (V-RBNN) methodology as a fast clustering method. The experimental results showthat the proposed method is able to detect 0.5 meter sUAV and its calculation time is under 20 millisecond perframes in complex background and long range conditions.
