Mission Planning Assessment For UAV Correction Methord

Mission planning system is an important content of unmanned aerial vehicle(UAV) related applied technolog ical, it allocates assignments to UAV, guides action direction of UAV. In recent year local wars, it plays a significant role in the war. In military applications in all countries of the world wide pay close attention to UAV. Path Planning is the key technology mission planning system, it’s also an important part of mission planning system, and the realization of intelligent navigation and safety technical guarantee to fulfil the task smoothly. Path Planning of its essential problem is seeking more optimization objective function solution under more the constraints, to solve the multi-objective function extremum problems. Planning the optimal or suboptimal route, which meets the needs of the task, it must be the high navigation accuracy, high safety route. It is important for UAV system to improve combat effectiveness. Thesis for the current UAV flight training and combat mission, Offline Route Planning lack of assessment, route practicality is not strong, online route planning is not timely corrected, UAV flight status of low safety factor, research assessment and correction method UAV Route Planning.Thesis for the physical properties of the constraints of UAV established UAV Route Planning mathematical model, analysis of the UAV flight e nvironmental constraints established environmental model, analysis of the potential threats UAV flight route source route planning to establish a threat source model. Set up the simulation environment, based on the five aspects to consider for UAV route correction simulation, one is based on the UAV detection radius of track is fixed; include irregular obstacles track is fixed; considering the emergency track is fixed; considering the target location changed track is fixed; considering variation of target track is fixed, the simulation results show that, in each case, heading Angle control quantity can meet the requirements of the biggest corner rate, the generated smooth track is effective and meet the requirements.Thesis summary and conclusion of the UAV Route Planning, it analyzes several typical programming algorithm, discussion O ffline Path Planning static evaluation algorithm, The main research is the route of UAV Penetration algorithm based on probability density of damage, flight constraint evaluation algorithm. Using the method of A* algorithm and B-spline theory to conduct UAV route online correction. Papers with a certain type of tactical UAV applications background, research assessment and correction method UAV Route Planning, design and implement a tactical UAV Route Planning Evaluation Software. The software focus on the UAV route data management capabilit ies, UAV route assessment function, UAV route and assess the results display, flight map operations, UAV route planning function again and situation plotting functions. The results show that the software has a good the human-computer interaction function, meet the actual application requirements of Route Planning.
