Research on a New IFF System and Signal Detection Method
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.
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…查看全部>>
