| 摘 要： | 复杂电磁环境下侦察伪码调相无线电引信信号时,很难截获一个伪码周期以上长度的信号,因此不能用常用的自相关峰值法测伪码序列周期.通过分析m序列三阶相关峰值点分布与伪码调相脉冲信号三阶相关极值点分布的关系,以及长短序列、长短信号三阶相关峰值点分布的对应情况,给出由三阶相关峰值位置估计伪码调相脉冲无线电引信信号伪码周期长度的方...

| Abstract: | In complex electromagnetic environment,it is difficult to intercept the signal longer than one PN period when setting up reconnaissance of the PN phase-modulated radio fuze signal,so the common method for measuring the period of PN sequence with self-correlation peaks is not applicable.Through analyzing the relationship between the distribution of third-order correlation peaks of the m-sequence and the distribution of third-order correlation peaks of the PN phase-modulated pulse signal,and the correspondenc... |
