With the trend of modern battlefield informatization and intelligence,UAV plays an important role in modern application.In the increasingly complex battlefield environment,multi-UAV cooperative operations have become an indispensable combat method in the military,and is also a hot point and difficulty in domestic and foreign researches in recent years.In this context,this paper studies the assignment of similar UAVs for two typical missions: cooperative reconnaissance and suppression of enemy air defense,and the results output the formation composition of the similar UAVs,the take-off sequence of each UAV in the formation and its target tasks,the amount of fuel carried by UAVs and the polyline route composed of waypoints.The main contents of this paper are as follows:(1)Through searching materials and reading literature,this paper analyzes and summarizes the research background and significance of this topic,as well as the research status of UAV task planning and multi-UAV task allocation at home and abroad.(2)A brief overview of the projects involved is given,and its working mode,formation flight mode,control methods and mission requirements are introduced.Then,from the perspective of reducing the flying cost of UAV formation and increasing the survival probability of UAV,the project is further studied and the corresponding improvement methods are proposed.(3)Aiming at the cooperative reconnaissance mode,a method of dividing the reconnaissance area based on the number of scan lines is developed,and a similar multi-UAV cooperative reconnaissance task assignment algorithm is designed.The accuracy and effectiveness of the algorithm are verified by examples.Then,this method is compared with the method of dividing the reconnaissance area evenly,and the results show that this method can not only shorten the overall range of UAV formation significantly,but also reduce the time spent by the whole formation to carry out the task.In addition,the multi-UAV task redistribution in dynamic environment further enriches the response strategies under different trigger redistribution conditions,and finally verifies its feasibility through examples.(4)Aiming at the enemy air defense suppression mode,a method of determining the take-off sequence of the UAV formation according to the required range of UAV mission is adopted,and this method is compared with the method of determining the take-off sequence according to the importance of the target point.It is proved that this method can effectively shorten the time of the whole UAV formation to complete the attack task.In addition,the problem of mission redistribution in the case of UAV failure and target point disappearance is studied,and its feasibility is verified by example analysis. |
