| 摘 要： | 介绍了一种新型敌我识别系统Mode 5 IFF,并分析了该系统的特点及信号产生流程。通过分析Mode 5 IFF系统询问及应答信号格式,提出了基于同步脉冲相关的Mode 5 IFF信号检测方法,该方法根据Mode 5 IFF信号同步脉冲数据一致性的特点,利用同步脉冲信号与所接收到的中频信号进行相关,取相关峰值达到Mode 5 IFF信号检测的目的。最后分析了该方法在"混扰"和低信噪比条件下的信号检测效果,验证了该方法的有效性。

| Abstract: | A new IFF system is introduced,its characteristics and signal processing course are analysed afterwards.By analysing the Mode 5 IFF signalformat,we presented a novel signal detection method based on the syncpulse correlation.This method comprises receiving a Intermediate Frequency(IF) signal,correlating the IF signal with a syncpulse signal,determing a correlation peak for the correlated signals.Finally,the effectiveness of the method is validated in the condition of overlaped and low SNR signals. |
