摘　　要：随着混沌理论的发展,混沌技术越来越多地应用在雷达领域。混沌序列由确定性系统产生,却有着随机序列的特性,具有白噪声统计特性、较理想的自相关和互相关特性以及产生简单、抗干扰能力强等特性。针对混沌幅度调制的高斯脉冲序列信号和基于混沌的脉冲位置调制方式在超宽带雷达中的应用进行了阐述,并提出混沌超宽带雷达实现方案。Along with chaos theory＇s development, the chaos technique is applied in the radar domain more and more. Chaos sequence is produced by the definite system, but it has the random sequence characteristic,for instance,it has white noise statistical property, more ideal autocorrelation and mutual correlation characteristic, to produce simply and strong antijamming ability and so on. The article elaborates the application of chaos amplitude modulation Gauss pulse sequence signal and pulse position modulation way basing on chaos in UWB- radar, and it also statements the realizing plan of chaos UWB- radar.
