摘　　要：跳频序列的设计是跳频通信的关键技术之一,采用直接式算法构造跳频序列,使用m序列对4分段Tent映射产生的序列进行重新排列。仿真结果表明,相对于直接采用4分段Tent映射产生的跳频序列,构造的跳频序列在保持均衡性和复杂度的条件下对独立性、汉明相关性、平均跳频间隔等方面的性能都有不同程度的提升,其中独立性的性能提升尤为突出。FH （Frequency Hopping） sequence is one of key technologies to FH communication. Direct- type algorithm is adopted to construct FH sequence, and with m sequence, the sequences generated by Tent -mapping with 4 subsections is rearranged. Simulation results show that compared with HF sequence gen- erated by initial Tent-mapping with 4 subsections, the sequences generated by the proposed algorithm, un- der the condition of maintaining balance and complexity and to varying degrees, enjoys the enhanced per- formance of independence, Hamming correlation and average FH interval, and in particular the index of in- dependence.
