| Abstract: | Chaotic FM signal has ideal auto-correlation performance and good Electronic Counter-Counter Measure (ECCM) capabilities like random signals. In this paper, a type of chaotic FM signal generated by Bernoulli map is used for ultra-wideband through-the-wall imaging. The signal model is also built. After analyzing the detection capability, resolution capability and anti-multipath interference performance of chaotic FM radar system, it is compared with the LFM radar system. Simulation result shows that the chaotic FM signal is better than the LFM signal in target detection, resolution and anti-multipath interference when it is applied to through-the-wall radar system. |
| Keywords: | Radar imaging Ultra-wideband Through-the-wall radar Chaotic FM signal |
