Research On Intelligent Communication Networking Methods Of Shipborne Aircraft Offshore Mission Formation

With the development of information warfare,the tactical application mode of shipborne aircraft develops along the path of single aircraft combat-cooperative combat-cluster network operations.At the same time,the aircraft is an important part of the integration of land,sea,air and space in the concept of network-centric warfare.Its networking capabilities and network performance will have an important impact on future war modes.However,the existing communication equipment transmission system is single,the network topology of low-altitude aircraft formation is time-varying,and the network is formed in three-dimensional space.The network communication routing algorithm is restricted by many aspects,which leads to insufficient stability,at the same time,when the aircraft is performing tasks in a low-altitude environment,the aircraft formation communication is susceptible to the interference of complex terrain fluctuations such as mountains,hills and various other ground base station signals,resulting in a decline in communication transmission capacity,damage to the network topology,and even the disconnection of islands and peaks.Therefore,in view of the above problems,this article will research from the following aspects.First of all,this thesis proposes the invulnerability evaluation index of the aircraft network,and based on the idea of active prevention,the Dijkstra algorithm,K-ink algorithm,and the network optimization method at different frequencies are used to construct multiple aircraft networks to deal with complex and changing networking environment.At the same time,the idea of table-driven routing is used to simulate the calculation of routing tables based on incomplete information,then the entire routing table network is supplemented with the idea of on-demand routing to solve the distributed networking problem of shipborne aircraft based on incomplete routing information.Then,a connectivity discrimination algorithm based on the union check is proposed to quickly detect the connectivity status of the aircraft formation network.When the network is partially damaged,the state information such as the altitude and aggregation degree of the aircraft formation is intelligently analyzed based on the AHP analytic method to make an intelligent decision.Then the trajectory adjustment method of the aircraft is provided to quickly integrate resources and reconstruct the wireless communication network.Finally,in unity3d,a real geographic environment was built based on the geographic information data of Yantai,Shandong.Then build the model of aircraft,use A Star algorithm to complete the automatic navigation function of the aircraft in the system,and use UDP technology to simulate the broadcast exchange of geographic information between aircraft.Then introduced the transmission model used in the simulation,constructed a route construction strategy for active prevention,lost connection adjustment module and other important UI interaction modules,built a carrier-based aircraft networking simulation system from scratch,simulated aircraft formation flight,communication,Networking,loss of connection,adjustment,and reconnection.
