Design And Implementation Of Transceiver For Data Link Of General UAV

UAV has become one of high-tech military hardware.It could replace manned aircraft to achieve zero casualties,high concealment,high mobility and reusable strategy.Data link is a key part of communication system in UAV.It could be described of bridge between command center and control unit.Data link communication ensures the accuracy,validity and reliability of information transmission.The keynote of this paper is to develop a kind of data link system with good performance.The task of this system is to exchange the information between the ground control center and communication system of UAV.This design combines the theory of data link system and the requirement of platform of UAV.It supplies the way to exchange the information among the task platform,the control platform,the monitoring platform and the sensor platform.So,the UAV could be controlled by the ground while carrying out the task.The main work of this design is as follows:1,Theoretical study.In the study of the subject,to read the relevant literature and books,to understand the principle of UAV platform.This design scheme combines the theoretical research of the project in the early stage.It includes the composition of each module of the data chain,the communication principles and algorithms in each module.2,Scheme demonstration.In order to ensure that the system could be completed we analyzed the working principles and implementation ways of the system,and demonstrated the detailed design of the project.3,Design&Testing.According to the previous overall plan design,each subsystem has been completed,including the design of the airborne system and the ground system.The function test is completed in the laboratory after the completion of the sample assembly.We completed the environmental adaptability test,including high and low temperature test,vibration test,EMC test and so on.It was loaded onto the UAV platform for completing combinative test after the internal test has been completed;It makes the performance of the system meet the design requirements according to rectify problems found in test.
