摘　　要：基于Logistic映射,提出一种由两个初值不同的Logistic映射组合产生混沌跳频序列的方法。对此组合映射混沌跳频序列的初值敏感性、汉明相关性、平衡性以及平均跳频间隔进行了分析。研究表明,此双Logistic组合映射产生的混沌跳频序列较单一的Logistic映射产生的混沌跳频序列具有好的初值敏感性,优良的汉明相关性,因此基于双Logistic组合映射产生的混沌跳频序列适合在跳频通信中使用。Based on Logistic-Mappi ng, this paper proposed a novel method of generating chaotic FH sequences, which consists of two Logistic maps with different initial values, and then analyzes the sensitivity to initial conditions, the Hamming correlation,balance and average frequency hopping intervals for these maps.The research shows that the sensitivity to initial conditions, the average frequency hopping intervals, and Hamming correlation and balance for the couple of Logistic maps are superior to single Logistic map. Thus the chaotic FH sequences generated by the couple of Logistic maps is suitable for communication.
