Chaotic FM signals for SAR jamming imaging

Chaotic FM signal is similar to random signal. A kind of chaotic series was generated using n-way Bernoulli map. The signals modulated by this kind of series have ideal auto-correlation property. High resolution image can be achieved using these signals. However, the waveform is very hard to estimate. In this paper, the chaotic FM signal model is discussed, and noise FM jamming image for SAR is analyzed. Using three kinds of noise FM signals for SAR target jamming image is simulated. The simulation result shows that ideal target jamming image can be achieved using chaotic FM signal, which has good prospects to be applied in imaging jamming radar system.
