跳频序列是跳频通信的关键技术之一，基于混沌映射产生跳频序列是目前较为常用的一种方式。针对单一映射产生的跳频序列存在抗预测能力不强和有限精度的问题，文章采用Jacobi序列扰动级联Logistic映射和Tent映射产生的跳频序列，并利用模d加余算法进行宽间隔处理的方法。仿真分析表明，文章所得到的跳频序列在均衡性，随机性，汉明相关性，复杂度以及平均跳频间隔等方面能够较好满足跳频通信对跳频序列的要求。

Frequency-hopping ( FH) sequence is one of the key technologies for FH communications. FH sequence generated from chaotic mapping is now a frequently-used method. Aiming at the problem of weak ability in anti-prediction and limited precision caused by single mapping, Jacobi sequences is adopted to perturb the FH sequence generated from cascaded Logistic mapping and Tent mapping, then by using the algorithm of mod d plus remainder,the wide interval is processed. Simulation analysis indicates that the proposed FH sequence could fairly satisfy the requirements of FH communication in balance, randomness, Hamming correlation, complexity and average FH interval.
