چکیده
In this paper, a tracking and pointing control system with dual-FSM (fast steering mirror) composite axis is proposed. It applied to the target-tracking accuracy in 3D GISC LiDAR (three-dimensional ghost imaging via sparsity constraint) system. The of proposed paper staring method multiple measurements, which mainly solves problem high-resolution remote-sensing high-speed moving targets when technology transformed into practical applications. research system, firstly, we propose that combines motion decoupling sensor solve mechanical coupling caused by noncoaxial installation FSM. Secondly, suppress inherent resonance FSM Thirdly, optical path design receiving aperture constraint. Finally, after sufficient experimental verification, our shown successfully reduce from 7% 0.6%, precision bandwidth reaches 300 Hz. Moreover, distance between target 2.74 km flight speed 7 m/s, improved 15.7 μrad (σ) 2.2 (σ), at same time, recognizes contour clearly. Our valuable put

Designing a predictive guidance and control system for maneuverable ground moving target tracking in 3D space using a Hexarotor
In this paper, the continuity of tracking a ground moving target using a Hexarotor is considered in the presence of sudden changes in direction, deceptive movements, temporary departure from the field of view (FOV) and changes in the height of the target. In this regard, a hierarchical guidance and control system for target tracking problem in an unknown environment and disturbances is proposed...
متن کاملDrogue Tracking Using 3D Flash LIDAR for Autonomous Aerial Refueling
Autonomous aerial refueling (AAR) is an important capability for an unmanned aerial vehicle (UAV) to increase its flying range and endurance without increasing its size. This paper presents a novel tracking method that utilizes both 2D intensity and 3D point-cloud data acquired with a 3D Flash LIDAR sensor to establish relative position and orientation between the receiver vehicle and drogue du...
متن کاملImproving the Imaging Quality of Ghost Imaging Lidar via Sparsity Constraint by Time-Resolved Technique
Ghost imaging via sparsity constraint (GISC)—which is developing into a new staring imaging lidar—can obtain both the range information and spatial distribution of a remote target with the use of the measurements below the Nyquist limit. In this work, schematics of both two-dimensional (2D) and three-dimensional (3D) GISC lidar are introduced. Compared with the 2D GISC lidar, we demonstrate by ...
متن کاملAn evaluation of dynamic object tracking with 3D LIDAR
This paper evaluates experimentally approaches to tracking dynamic objects using 3D LIDAR data such as that obtained from a Velodyne HDL-64. Whilst many algorithms exist for tracking objects in 2D laser data, only recently have algorithms which model the 3D appearance of tracked objects been proposed. The benefits of these algorithms with respect to model free centroid based methods have not be...
