中文摘要：

依据混沌系统的脉冲同步特性，结合数字信号处理技术，可以得到原发射信号的时间延迟信号与变时间尺度信号，据此提出脉冲同步技术在混沌雷达系统中的应用方案，给出连续混沌信号雷达的结构框架。仿真实例以Colpitts电路产生的混沌信号为雷达发射信号，验证了基于脉冲同步的混沌信号时延与变时间尺度技术应用于混沌雷达的可行性。混沌雷达系统中的信号处理部分以宽带互模糊函数为工具，根据宽带模糊函数的定义给出了混沌信号雷达信号处理部分的详细框图。

英文摘要：

According as the characteristic of impulsive synchronization of chaotic system, combined with digital signal processing technology, we can use impulsive synchronization theory to produce chaotic time-delay and time-scaling versions, based on the above, the blue print of coherent chaotic radar and block diagram is brought forward. A simulation example using the chaotic signal generated by Colpitts circuit as radar transmitted signal proves that impulsive synchronization technology exhibiting the time- delay and time-scaling versions of chaotic signal is feasible. Furthermore founded with the definition of wideband cross ambiguity function, the technique finds its application in chaotic signal radar.
