Link Quality Analysis And Networking Technology Of JTIDS

Information is the key point and core of modern weaponry. Data link is the basis of the information,as well as the key equipment to improve collaboration capabilities, accelerate the speed of response towarfare, acquire the advantage of information communication. Date link can realize the exchange ofreal-time transmission of data between sensor platform, control platforms and weapons platforms,transmitting real-time information of battlefield situation, cooperative control, command guidance,and weapons hinge, mainly based on wireless channel, with the unified data formats andcommunication protocols. The most typical case is Joint Tactical Information Distribution System ofUS Army. And the problem of data link networking is greatly emphasized in recent years by variousdepartments, especially under the current condition that the quantity of transmission platforms islimited, thus it is quiet urgent to make JTIDS ground network into practice.In this paper, we firstly analyze the level and the development of domestic and international datachain, introduce its essential role in modern war. By deeply analyzing the operation principles ofJTIDS, we preliminary simulate related equipment and performance of JTIDS. Secondly, this paperaccess and research on the data link communication quality between the site and Air Force platformby analyzing data chain link quality in depth. Ultimately, this paper research on the handoverjudgment, switching site selection method, and hand switch control method in the date link of JTIDS,promote an efficient handover judgment and switching site selection method, design an efficienthandover switching control method, by means of state real-time monitoring, real-time collection ofcurrent location of the aerial platform and data link state。...
