Research On The Jamming Technology Of Satellite Communication

In today’s society, due to the rapid development and wide application ofinformation systems technology about the integration of the space, air and land,information holds a significant position in military communications, thus it is seizingthe opportunity of controlling the information that plays an important role in thecompetitive war. Therefore, in satellite communications, how to protect ones ownsecurity and access and transmit information smoothly, and how to stop and destroythe enemy’s access to the information has become an important subject to beresearched at home and abroad.The jamming technology in satellite communications is mainly researched in thisthesis. Through the analysis and comparison of many available typical blanketjamming methods, a noise FM jamming method is given, and a new jamming calledretransmitted jamming technology is researched. In this paper, the satellitecommunication model, the retransmitted jamming technology and the blanket jammingmode are established and debugged with SIMULINK simulation software, by whichwe can get the result of the different parameters acting on the performance of satellitelinks. Through the comparison of blanket jamming technology and retransmittedjamming technology, the error performances of different interference are reached.Finally, the conclusion that retransmitted jamming technology is better than blanketjamming technology is obtained.
