Route Planning And Design In Electronic Reconnaissance Aircraft’s Tasks

The electronic reconnaissance aircraft is a special combat aircraft,the mission system is mainly equipped with electronic reconnaissance system,optical imaging system,microwave imaging systems and other equipment,used for reconnaissance and surveillance on the sensitive area of the key goal,is an important means to obtain information at home and abroad.In the electronic reconnaissance aircraft reconnaissance missions,in order to improve the efficiency of electronic reconnaissance aircraft reconnaissance,to ensure their own safety,must according to the enemy threat information or terrain information for electronic reconnaissance aircraft designed a suitable flight route.This paper focuses on the route planning problem under different mission requirements of electronic reconnaissance aircraft.The main work of the paper is as follows:1.Firstly,according to the electronic reconnaissance aircraft mission requirements,introduced the threat model and constraints in route planning,analyzes the application scene of several commonly used route planning algorithm and the advantages and disadvantages,and focus on the sparse A* algorithm based on improved A* algorithm(SAS)and particle swarm optimization(PSO)algorithm.2.In view of the application of sparse A* search algorithm in track planning,first,the reconnaissance space of electronic reconnaissance aircraft is divided,then the cost function in the algorithm is designed and the constraint conditions of electronic reconnaissance aircraft are combined to generate the reconnaissance route which satisfies the actual reconnaissance flight under certain conditions3.According to the application of particle swarm optimization in route planning,under the condition of certain fitness function,the parameters of particle swarm optimization are reasonably valued,and the optimal track for electronic reconnaissance aircraft to perform reconnaissance mission is planned in the whole situation.At the same time,the excellent performance of the sparse A* algorithm in avoiding threats will be combined.The particle swarm optimization(PSO)and sparse A* algorithm are combined to generate the optimal reconnaissance route not only to meet the needs of reconnaissance but also to meet the security requirements,and to meet the practical application requirements of the electronic reconnaissance aircraft.4.Finally,according to the demand of the system design and implementation of software path planning of electronic reconnaissance aircraft,in the process of software design,the object oriented programming,C# and MATLAB joint programming,focusing on the route planning algorithm,XML document design,digital map display,display a list of the main functions of the route Module design and implementation,and to track the planning of the smooth route optimization,this software has been applied to actual equipment,electronic reconnaissance aircraft path planning can meet the practical application needs.
