摘　　要：为了提升多用户跳频系统在复杂场景下的顽存能力,提出了一种基于成熟的混沌序列构造性能优良的无碰撞区跳频序列集的方法。与已有的无碰撞区跳频序列构造方法相比,该方法能够利用已有混沌序列在高复杂度和长周期性能方面的良好性质,构造的序列集能够达到非汉明相关的理论界。理论分析和仿真结果表明,该方法构造的序列具有更好的均匀性、随机性、复杂度等统计特性,为跳频通信系统在多用户组网通信应用时提供更强的安全可靠性。In order to improve the survivability of multi-user frequency hopping systems in complex electronic scenarios,a method is proposed to construct no-hit-zone frequency hopping sequence set based on mature chaotic sequences.Compared with the existing methods for constructing no-hit-zone frequency hopping sequences,this method can utilize the excellent properties of existing chaotic sequences in terms of high complexity and long-period performance,and the constructed sequence set reaches the theoretical bound of Hamming correlation.The theoretical analysis and simulation results show that the sequences constructed by the proposed method have better statistical properties such as uniformity,randomness,and complexity,and are more resistant to deciphering in no-hit-zone frequency hopping communication systems.
