摘要：

Chaotic FM signal is similar to random signal. It has good electronic counter-countermeasure (ECCM) capabilities. In this paper, chaotic FM signal is used to improve the ECCM capabilities of Synthetic Aperture Radar (SAR). 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 point target imaging is simulated. The simulation result shows that ideal point target image can be achieved using chaotic FM signal, which has good prospects to be applied in imaging radar system.
