Research On Air-to-ground Reconnaissance Mission Planning System Of UAV

In modern war, unmanned aerial vehicle (UAV) is increasingly being used by various countriesas a kind of important reconnaissance force. In the situation of the development of UAV，and in theface of more furious and complicated war environment，how to further develop UAV’s missionplanning technology has important military and theoretical significance。For this reason, this paper focuses on the function of the UAV’s mission planning.The missionplanning system is divided into the task planning and route planning two aspects, and the relevantresearch work are deeply unfolded.First of all, according to the specific type of threats, this paper puts forward the mathematicalmodel of each single threat: radar, ground-to-air missile and archibald, and at the same time calculatesthe blind area of the radar.This paper also analyses digital terrain generation technique. And commondigital terrain algorithms are simulated。Secondly, the UAV’s task planning system is analysed，and the relevant model is established. Wedivide the task planning system into reconnaissance area transfer subsystem, reconnaissance routesdata subsystem, reconnaissance tasks allocation subsystem, sensors management subsystem andonline real-time re-planning subsystem. Each subsystem is further discussed, and then we reach thetask planning system.Then, we use the improved SAS algorithm to calculate the off-time route, and the differentialevolution algorithm is also introduced in the route planning. Then we use DSAS algorithm to trackonline real-time route re-planning, and get real-time optimal route.Finally, by VC++software, we realize the task planning system programming，and then realizethe whole software system’s simulation through a specific task instance.
