摘　　要：提出了一种用混沌映射方法产生党间隔跳频序列的方法，分析了混沌宽间隔跳频序列的平衡特性及汉明相关特性，并讨论了序列的线性复杂度和抗破译能力。实验表明，该跳频序列性能良好，适用于短波跳频系统。A new method is proposed to generate FH sequences with given minimum gap from chaotic map. The sequences characteristics of balance property and Hamming correlation are analyzed in this paper. we also discussed the linear complexity and the anti-decipher ability of the sequences. It is shown through experiments that those FH sequences have excellent properties andcan be applied in short wave FH system.
