Enhanced Synthetic Vision Visualization Processing Technology For Cooperative Combat Control Stations

UAV(unmanned aerial vehicle)are becoming more powerful,with the development of UAV's technologies.UAV play a major role in today's military and civilian fields.However,the autonomy of UAV is limited,and UAV still need the control of operators in complex environments.And the operator's perception and understanding of the operational environment are the key to controlling UAV operations.Compared with single UAV,multi-UAVs are undoubtedly more advantageous in a complex operational environment.Therefore,in the complex environment,how to use the multi-UAVs to make cooperative combat and how to improve the operator's situational awareness and understanding capabilities,and thus reduce the workload of the operator and complete the combat mission have become the main research topic of this article.Firstly,the article introduces the current status of UAV and describes the advantages of cooperative combat for multi-UAVs relative to a single UAV,proposes the enhanced synthetic vision technology to enhance the operator's perception and understanding of the operational environment.And the enhanced synthetic vision system and its current status are described.Secondly,through visual simulation technology,this paper has successively designed and completed the coordinated operation environment,and the multi-UAV perception and ground-to-air collaboration operation.Finally,the visual simulation technology is used to complete the design and implementation of this paper's coordinated operations.The specific work accomplished in this paper has the following aspects:1.Research on the enhanced synthetic vision system and its current status,and reference to two projects of foreign multi-UAVs formation coordination and ground-to-air collaboration.Use the relevant status quo as a reference for research,and combine with the purpose of this study to design and implement.2.Research on the construction of a coordinated operational environment.With the help of enhanced synthetic vision terrain database technology and 3D visual simulation technology,the components of a collaborative operational environment are realized through corresponding software tools.According to the environmental needs of different coordinated operations,a variety of coordinated operational environments have been created.3.Design and implement a multi-UAVs cooperative awareness program.A multi-UAVs integrated control system is designed and implemented.According to the autonomy reference of existing UAVs,multi-UAVs visual range superimposed collaborative reconnaissance and multi-UAVs autonomous obstacle avoidance are achieved;and through the implementation of enhanced synthetic visual sensor technology,cooperative reconnaissance of multi-UAVs with multi-sensors are realized.4.Designed and implemented a land-air cooperative combat plan for the commanding soldier and multi-UAVs in an urban environment.The soldier can share information with multi-UAVs and highlight operational information through certain icons to improve the soldier's perception and understanding.According to the different needs of the combat phase,the soldier can select and command the multi-UAVs with different functions to combat,thereby improving the soldiers' own perception ability,attack ability,movement ability and safety.5.Research and realization of the demonstration platform for the enhanced synthetic vision visualization technology of collaborative combat control station.The technical route and system design of the final demonstration platform are studied,and the interface of the final demonstration platform is completed.For the designed collaborative operation environment,the multi-UAV cooperative sensing program and the ground-to-air collaboration program are simulated and verified.
