Research on a New IFF System and Signal Detection Method

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.
