摘　　要：在跳频系统中,跳频序列的性能是评价跳频系统的性能的重要指标。本文给出了两种二维非周期低碰撞区跳频序列的构造方法。首先,利用笛卡尔积构造二维非期低碰撞区跳频序列集。然后,利用交织法构造二维非周期低碰撞区跳频序列集。最后,分析了新的跳频序列集在二维低碰撞区内的非周期汉明相关性,并根据理论界对序列集进行了最优性分析。In the frequency hopping system, the performance of frequency hopping sequence is the main index to evaluate the performance of frequency hopping communication system. Two methods are put forward for constructing frequency hopping sequences with the two-dimensional aperiodic low hit zone. Firstly, the frequency hopping sequence set with the two-dimensional aperiodic low hit zone by the Cartesian product is constructed. Secondly, the frequency hopping sequence set with the two-dimensional aperiodic low hit zone by the interleaving technique is constructed. Finally, the new frequency hopping sequence set’ aperiodic hamming correlation is analyzed in the two-dimensional low hit zone, and according to the theoretical bound, the optimal analysis of the sequence set is carried out.
