摘　　要：在跳频通信系统中,具有良好汉明相关性能的跳频序列对于系统的性能至关重要。构造性能优良的跳频序列成为研究跳频技术的重要方向。基于交织法构造出了两类时频二维周期汉明相关跳频序列集。新构造出的序列集关于理论界是最优的,并且序列集中的序列数目更多、序列的长度更长,有利于提高系统的抗干扰性能。In the frequency hopping communication system,frequency hopping sequences(FHSs)with good hamming correlation performances are critical to the performance of system.Constructions of FHSs with good performances have become an important research direction of frequency hopping technology.In this paper,two classes of FHSs with optimal time-frequency two-dimensional hamming correlation performance are constructed based on interleaving technique.The frequency hopping sequence(FHS)set constructed by this method is optimal about the theoretical bound,and the number of sequences in the sequence set is more,the length of sequences is longer,which is beneficial to improve the anti-interference performance of the system.
