Target Location And Landing Based On Unmanned Aerial Vehicle

For its small volume, light weight, good mobility and long time of flight, andhandy concealment, unmanned aerial vehicle (UAV) is playing an increasinglyimportant role in the modern war. In recent years, the unmanned aerial vehicle (UAV)research becomes more extensive and deeply. Specific to the unmanned aerial vehicle(UAV) platform, this article some research about target passive location and theauxiliary landing.Passive location is applied to the UAV reconnaissance and attack，including statictarget and moving target positioning of the object. According to the criteria to determinewhether a target moving target first, and then achieve the function positioning. In thestationary target localization process, this paper uses the unmanned aerial vehicle (UAV)azimuth angle and its rate of change during his flight, use for a target real-time passiveranging method to accurately work out the distance form the target to the unmannedaerial vehicle (UAV), and then use the extended kalman filter to depose the result. Inthe process of positioning for moving targets, this paper uses the unmanned aerialvehicle (UAV) azimuth angle and its rate of change during his flight. in the help of themethod of least square, this paper get the target motion parameters after muchmeasurement.In order to satisfy the requirement of the unmanned aerial vehicle (UAV) recyclingand reuse, this article do some research in unmanned aerial vehicle (UAV) landingbased on the visual navigation system. When unmanned aerial vehicle (UAV) searchand track the runway, firstly, dispose runway images form the airborne camera, and thenuse the template matching to find the position of the runway so as to realize the trackingof the runway； In process of unmanned aerial vehicle (UAV) landing posture andposition measurement, this paper improves the traditional double circular template,joined the sub-pixel processing, thus get the more accurate result of the unmanned aerialvehicle (UAV) landing posture and position,；At the unmanned aerial vehicle (UAV)automatic landing control aspect, this paper measured the UAV attitude and orientationvalue coupled with unmanned aerial vehicle (UAV) landing indicator, design theunmanned aerial vehicle (UAV) landing trajectory and a simulation was carried out.
