In order to improve the RF stealth performance of frequency hopping system , a design method for hopping cycle of RF stealth based on chaotic sequences is proposed by using the uncertainty strategy of signal parameters .In this design , the chaotic sequences are generated by Logistic mapping , and the frequency hopping cycle space is mapped to achieve the control on hopping cycle parameters of hopping signals .The simulation results show that the proposed method is much better than the traditional fixed cycle method , it has better RF stealth performance .%为提高跳频系统的射频隐身性能，利用信号参数的不确定性策略，提出了一种基于混沌序列的射频隐身跳频周期设计方法。该方法采用Logistic映射生成混沌序列，并将其在跳频周期空间进行映射，以实现对跳频信号的跳频周期参数控制。仿真结果表明，本文所提方法的不确定性远优于传统固定周期方法，具有更好的射频隐身性能。
