摘　　要：提出了一种基于混沌电路的随机脉位调制 (RPPM)和随机二相码调相 (RBCPM)混合调制的雷达引信系统。介绍了该引信波形的数学模型、平均模糊函数及引信的实现框图和工作原理 ,研究了基于混沌电路的混合调制信号的产生方法。这种引信波形不仅具有结构简单和易于处理等特点 ,而且具有良好的测距和测速性能 。This paper proposes a radar fuze system based on chaos circuit. It's signal waveform modulation is the mixed modulation waveform of random pulse position modulation and random binary coded phase modulation. The mathematical model of the fuze signal waveform is defined and its average ambiguity function is analyzed. The fuze system implementation is given and its principle is present. Then the generation method of mixed signal based on chaos circuit is studied. This kind of radar fuze has not only the advantages of simple structure and easy processing, but also good range and velocity measurement performances, very low intercepted probability, and excellent anti interferences.
