With the increasingly complex combat environment of modern battlefield,weapon equipment systems and combat modes are becoming more advanced,fierce offensive and defensive multi-level confrontations have become the norm,and the feasibility of relying on single-missile penetration has been greatly reduced.The DSP-based cooperative mission planning system of multi-UAV provides high-performance on-board computing capabilities,combined with high-level cooperative mission planning technical solutions,can greatly increase the possibility of penetration and dominate the situation in modern battle,which is one of the focuses of military research in various countries.Cooperative mission planning of multi-UAV is a complex multi-objective decision-making,and optimization problem under multiple constraints.It is necessary to synthesize multiple strategies to formulate a mission plan,and ensure the overall combat effectiveness of multiUAV system.Therefore,this thesis focuses on the DSP-based cooperative mission planning technology of multi-fixed-wing-UAV,and the main results are as follows:(1)The DSP-based cooperative mission planner of multi-UAV is designed,which can effectively realize the online cooperative task allocation of multi-UAV and complete the flight and communication capabilities of multi-UAV collaborative operations.Firstly,in response to the needs of drones for collaborative tasks,a design overview is proposed for the DSP-based cooperative mission planner of multi-UAV.Secondly,the solution is designed as the data storage ad hoc network module and communication data package of the DSPbased cooperative mission planner.Finally,we provide two typical DSP multi-UAV cooperative mission planner design solutions.(2)A trajectory planning method of multi-UAV with improved A* algorithm is designed,which can effectively realize the rapid planning of multi-UAV feasible routes in complex mountainous areas.Firstly,combined with the flight characteristics of the UAV,the search space of the A* algorithm is improved,so that it can complete the trajectory planning at a fixed angle of incidence,and complete the rapid search method of the complex route in the mountain area by adding guide points.Secondly,combined with the problem scene of the complex mountainous area,an A* algorithm of adding guidance points is provided.Finally,the collision detection of multi UAV tracks is carried out by further combining the spacetime cooperative constraint of multi UAV to realize the cooperative route planning of multi UAV.(3)A genetic algorithm solution plan is designed,which can effectively solve the mission planning of multi-UAV.Firstly,the constraints of the task scenario are modeled,and the cost function of constraints is provided.Secondly,the genotype,mutation operator,crossover operator and fitness function are designed based on genetic algorithm for cooperative mission planning of multi-UAV.Finally,the feasibility of the scheme was verified through simulation.(4)By using multiple unmanned vehicles as the platform,it is verified that the DSP-based cooperative mission planner of multi-UAV has the performance of module replacement,task online decision-making,and safe and stable operation.
