On-Line Path Planning Algorithm for UCAVs

GAO Ruizhou,CHEN Shaodong,ZOU Qingyuan(Luoyang Institute of Electro-Optical Equipment,AVIC,Luoyang 471009,China)  
On-line path planning capability is very important for a single Uninhabited Combat Aerial Vehicle(UCAV) in carrying out autonomous ground attack missions.In grid-format digital map,through improvements to threat modeling,data-structure organization,cost-estimate function and optimum algorithm,an improved path planning model is put forward based on A* algorithm.The algorithm can reduce the search space and thus improve the real-time performance while guarantee the effectiveness of the path planning.Simulation result showed that the model can greatly reduce the dependency of the path planning effect on accuracy of the grid-format digital map,which supplies a reference for further study on-line path planning and real-time route replanning of UCAV.
