| 摘 要： | 提出一套基于混沌理论的二相、多相编码信号以及混沌二相--线性调频复合调制信号的形成与处理方案,可应用于搜索雷达系统,实现多波形形式、多波形参数和宽带多频率捷变的雷达波形产生及相关压缩处理.重点论述了一类基于Logistic映射的混沌二相编码信号、两种形式的混沌二相--线性调频复合调制信号和混沌泰勒四相编码信号的设计原理与主要处理方法,并应用加权网络对上述脉冲压缩信号进行旁瓣抑制.计算机仿真结果表明,上述三类信号的主要性能均满足系统指标要求,从而使该方案具备很强的低截获及抗干扰能力.

| Abstract: | A design of a chaotic phase-coded signal formation and processing system is proposed,which can be used for surveillance radar.And three types of signals: a chaotic binary coded signal,two types of combination of chaotic binary and linear frequency modulated signal,a chaotic Taylor 4-phase coded signal are studied,including their principles,design process and weighted network method for side lobe suppression.All the simulation results meet the requiments of system,thus improving the low-interception probability and anti-jamming capability of the radar system. |
