摘　　要：为了增强跳频通信系统的保密性和安全性,基于Logistic映射和Hybird映射方法的组合,采用相邻组合的方法来产生混沌跳频序列。仿真检测了包括初始敏感性、平衡性、汉明相关性在内的系统性能,结果表明:新跳频序列能够很好地克服有限精度效应,初始敏感性高,汉明相关性好,并具有较高的平衡性能。Based on the combination of Logistic map and Hybird map, a method with combined map to generate chaotic frequency hopping（FH） sequences is proposed in order to enhance the properties of secrecy and security in traditional FH systems. The properties of new sequence are simulated including initial sensitivity, balance and Hamming correlation. Simulation results show that the new chaotic FH sequence can easily overcome the problem of finite precision effect, besides, it has higher initial sensitivity, better Hamming correlation property and higher balance property.
