| 摘 要： | 基于Tent映射和Logistic映射，从增大混沌跳频序列的线性复杂度与增强跳频系统的安全保密性出发，提出了一种组合混沌映射产生混沌跳频序列的方法。从理论上对该跳频序列的平衡性、相关性进行了分析，并用MATLAB语言进行了数值模拟，研究表明：其模拟结果与理论分析是一致的。同时，与几种单一混沌映射所产生的混沌跳频序列进行了比较，证明了该方法是可行的。

| Abstract: | Based on Tent map and Logistic map, this paper presents a method to generate chaotic frequency hopping (FH) sequences through combined chaotic map in order to augment the linear complication of chaotic FH sequences and boost up the secrecy and security of FH system. It analyzes the balance and correlation of this FH sequences theoretically and performs numerical value simulation with MATLAB language. The study shows that the simulated results accord with the theoretical analysis. Meanwhile the method is compared with other single chaotic maps and proved feasible. |
