Research on application of nonlinear system in communication jamming

In this paper, the application of chaos in communication jamming is investigated. We first develop a nonlinear system which acts as a guide unit of jamming and the system is in a state of chaos. Then the jamming signal is set to be the output of the chaotic nonlinear system. Jamming effects and jamming levels of the system driven by different enemy communication signals are thus studied and compared with the effects and levels of white noise blanketing jamming. Simulation results show that the jamming signal can cover corresponding enemy communication signal in frequency domain and get fine jamming effects. Finally, we conclude that the jamming effects of the system mentioned above are obviously better than the effects of white noise blanketing jamming. Furthermore, if the frequency points of enemy communication signal are in the pass band of the nonlinear system frequency spectrum, the communication jamming system achieves an optimal effect of jamming.
