一种新颖的组合混沌宽间隔跳频序列

为增强跳频通信抗窄带干扰和抗跟踪干扰的能力，对组合混沌映射的实值序列排序量化，产生排序序列，再对排序序列进行宽间隔重置，构造宽间隔跳频序列。仿真分析表明，所提序列的均匀性、汉明相关性和跳频间隔分布特性良好，优于基于 Logistic 混沌序列的随机平移替代和对偶频带宽间隔跳频序列。

New FH Sequence with Wide Gap Based on Combined Chaotic

To enhance the performance of anti-narrow-band-interference and anti-follower-jamming in frequency hopping communication system, a new FH sequence with wide gap is proposed in this paper. The method generates chaotic sequence through combined map and ranking quantization, and constructs wide gap FH sequence by permuting the chaotic sequence. Simulation and analysis results show that the proposed FH sequences have better performance in uniformity, hamming correlation and circle gap distribution compared with the common wide gap sequences of Radom-Shift-Replace method and Dual-Band method based on Logistic chaotic map.
