中文摘要：
分析复合离散混沌系统．针对该混沌系统研究了一种伪随机序列的生成方法。利用上述方法生成复合离散混沌序列，对正弦波进行调制，得到复合离散混沌二相编码信号，对该信号的自相关性、频谱、模糊函数和抗干扰等性能进行了分析，并给出了相应的仿真结果。仿真结果表明．该信号具有优良的具有距离和速度分辨率较强的抗干扰能力。
英文摘要：
Analyses composite discrete chaotic system, resrarches on a generated method of pseudorandom sequence based on this chaotic system. Composite discrete chaotic sequence is generated using this method, the sine wave is modulated by this chaotic sequence and the Composite discrete chaotic hi-phase encoding signal is attained. Based on the foundation of simulations, researches on the performances of auto-correlation, spectra and ambiguity function of this signal. The simulation results show that the resolutions of this signal in both range and velocity domine are good, the anti-interference performance of this signal is fine.
