Electro-Optical Tracking System for UAVs
A uav electro optical tracking system is an important equipment for a mission-oriented unmanned aerial vehicle (UAV). It can track targets and take 3-D measurement of a target. However, since the distance between a UAV and a target is very large, slight measurement errors will be magnified. Therefore, precise target location is a critical factor for the performance of the EOSTP. In this paper, we present a method to locate the position of a target by integrating the tracking and 3-D measurement into one system. This is accomplished by introducing a new LPV based estimation algorithm and performing flight tests to verify its performance.
The main function of a uav electro optical tracking system is to detect moving targets in the designed area and send the information to the radar system. Then, the radar and electro-optical equipment will automatically capture and track the moving target. Moreover, the system can display the target trace, tracking status and other working parameters of the equipment on the display screen.
A uav electro optical tracking system uses an imaging sensor to provide real-time long-range automated target identification, tracking and video recording for terrestrial, airborne and Earth-orbiting objects. It can help improve infrastructure monitoring and surveillance, reduce costs for range safety and provide vital data on orbiting debris to protect Earth and space systems from collisions.
This uav electro optical tracking system uses a high-resolution lens to provide a sharp image of the target. Its software is programmed to recognize the client’s unique parameters and enables it to provide optimal performance for specific applications. It also features a built-in computer and storage for data processing and display, making it an effective tool for security purposes.
The uav electro optical tracking system consists of the hardware system on the UAV, Ground Control System (GCS) and Electronics on Board (EOS). The GCS is responsible for the power supply, control interface and the operation of the EOS. It controls the servo drives for the gimbals, the pan/tilt, and the EO/IR modules. It also monitors the performance of each gimbal and communicates with the GPS on the ground station.
Coarse to fine pointing, acquisition and tracking (PAT) approaches are required for UAV-based FSO communication systems to establish a reliable link. These approaches need to consider both transmitter and receiver angle of arrival (AoA) fluctuations in order to compensate for the vibrations introduced by a UAV’s expected movements.
A hybrid PAT mechanism proposed by Xiu et al. combines an FSM with a gimbal on the UAV to achieve optimal performance and minimize weight. In addition to its high flexibility, the SLM can perform beam divergence which makes it particularly suitable for the fine pointing stage. This approach has been verified in flight tests by comparing its results with those of conventional gimbal and FSM-based systems. The results suggest that the use of a SLM in the fine pointing stage can achieve higher performance than those of conventional PAT systems.
