摘 要:为了提高对偶频带法宽间隔跳频序列的周期性、随机性、归一化汉明相关性、频隙数及跳频间隔,提出了一种新的非线性宽间隔跳频序列的构造方法。该构造方法通过引入双素数序列扩展了跳频码的周期,采用非线性宽间隔处理方法对对偶频带法进行改进,提高了对偶频带法宽间隔跳频序列的各项性能,尤其是随机性和抗破译性。通过MATLAB仿真表明,该跳频序列的性能优于传统的非宽间隔跳频序列以及对偶频带法宽间隔跳频序列,从而提高了跳频通信系统对抗各种干扰能力和抗捕获能力。In order to improve the cyclical, normalized autocorrelation property, normalized cross-correlation characteristics, the frequency gap and average hopping interval performance of the dual frequency band method, a new method of nonlinear wide interval frequency hopping sequence was proposed. It expanded the cycle of fre- quency hopping code sequence by introducing dual primes, improved various performance of dual band wide in- terval frequency hopping sequence, especially the randomness and the crack resistance. MATLAB simulation showed that the performance were better than traditional frequency hopping sequences without given minimum gap, also better than the frequency hopping sequences generated by the dual frequency band method. It improves the frequency hopping communication system against various interference abilitv and anti-capturing ability.
