摘　　要：混沌信号是一种类随机性信号,具有极强的抗干扰性和极低的截获概率,越来越多地应用在雷达领域。混沌序列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。文中针对混沌幅度调制、混沌脉冲位置调制和混沌脉冲位置与脉冲相位复合调制的雷达信号在超宽带雷达中的应用进行了分析,并对混沌超宽带雷达的特点、实现方法进行了阐述。Chaos signal is a kind of quasi-random signal, it has strong anti-interference characteristic and very low interception probability, so it is being applied in the radar more and more. Chaotic sequence has many features such as white-noise statistical properties, ideal autocorrelation and cross correlation properties, and is generated simply with strong anti-interference ability. This paper presents application of radar signal with chaotic amplitude modulation, chaotic pulse position modulation, chaotic pulse position and pulse-phase composite modulation in UWB radar. It also describes the feature and implementation of chaos UWB radar.
