摘　　要：针对传统跳频同步中同步引导码易被敌方干扰的缺点,提出了基于序列部分频点匹配的自同步方案。该方案在不使用同步引导码的情况下,按照序列部分频点匹配的同步方案,任意设定接收频点,根据频点间隔特征信息在本地已知跳频序列中进行搜索匹配,进而计算出跳频序列收发两端的相位差,从而调整相位差实现跳频同步。理论分析与仿真实验结果表明,基于序列部分频点匹配的自同步方案在捕获时间上优于串行同步捕获方案,就复杂度而言,相较于并行同步捕获方案有了很大的降低,同时该方案不需要同步引导码,提高了抗干扰的性能。Aiming at the disadvantage that the synchronization pilot code is liable to the traditional frequency hopping synchronization interference,a self-synchronization scheme based on sequence partial frequency point matching was proposed.Without using synchronous pilot code,the scheme arbitrarily set the receiving frequency points according to the synchronization scheme of partial frequency point matching,searched and matched the local known frequency hopping sequence according to the characteristic information of frequency point interval,and then calculated the phase difference between the begining and end of the frequency hopping sequence,so as to adjust the phase difference to achieve frequency hopping synchronization.The theoretical analysis and simulation results showed that the self-synchronization scheme based on sequence partial frequency matching was better than the serial synchronization acquisition scheme in acquisition time.Compared with the parallel synchronization acquisition scheme,the complexity of the scheme was greatly reduced.At the same time,for the scheme did not need synchronization pilot code and improved the anti-jamming performance.
