The Study Of Electronic Jamming Technology Based On Chaos Theory

With the development of information technology, the styles and theories about modern warfare have been changing greatly. In this great new tide of military reform over the world, the technology of electronic jamming and anti-jamming has played key roles.In this thesis, the feature and development for modern warfare is presented. The technology of electronic jamming and anti-jamming in all important links in modern warfare is also detailed, including the basic concept, basic classify, technical theory and practical application. For the chaos'application in electronic interference, the thorough studies are presented. A new scheme, chaos time-variable system, is proposed.In the aspect of electronic interference to the facilities on the ground, it is mainly presented for the field communication network, radar and ship. In the electronic jamming to the plane and satellite, the jamming pod on the plane, military satellite and GPS are referred. In the interference to the missile and remote signal, the interference to the auto-search missile is recommended. Meanwhile, the computer simulation for the RGPO (Range—Gate Pull—Off) is proceeded and the method of RGPO is proved to be effective.Lastly, it is introduced for chaos'application in electronic jamming. It includes the detecting technology for weak signal and chaos security communication. For the detection of weak signal, the adaptive filter detection and Duffing detection are presented and the simulation by Duffing detection is proceeded. For the chaos security communication, the Chua's circuit is used in the modulation and demodulation and the simulation is proceeded. The influence to the quality of communication system is also analyzed in this Chua's circuit.A new scheme in chaos security communication, the time-variable system added in the transmission and reception unit, is proposed in this paper. This way can make the system be double-secure. Paper also point out the condition of system's transfer function that the time-variable system must require.Chaos technology is still at the edge phase for exploration. There will be great theoretical and practical significance when every new technology is acquired in the field, whether in the military electronic jamming or in the other fields.
