| 摘 要： | 针对采用模拟电路设计的混沌信号源存在结构复杂、可靠性低、噪声高、精度低等缺点，致使其在保密通信、雷达与通信对抗等领域中出现难以可靠应用的情况，以Lorenz系统为例，采用DSP设计并实现混沌信号源，并运用简单有效的JTAG测试技术和CCS在线调试功能，直接访问DSP内存，验证混沌信号。同时，又实现Liu系统混沌信号源，从而证明该信号源模块具有很强的通用性和灵活性。

| Abstract: | Due to the disadvantages,such as complex structure,low reliability,high noise,low precision and so on,so the chaotic signal source designed by analog circuit can not be well applied.This paper takes Lorenz system for example,designs a chaotic signal source with DSP and verifies the chaotic signal with testing technology of JTAG and on-line debugging function of CCS,besides,realizes chaotic signal source of Liu system.So it proves that this chaotic signal source is general and flexible. |
