| Abstract: | In view of the difficulty caused by nonperiodic characteristic of frequency hopping sequence and the similar time and frequency characteristics to the general shortwave frequency hopping signal for detecting the differential frequency hopping(DFH) signal without parameters,an algorithm is proposed for detecting the DFH signal based on multi-hop autocorrelation.Utilizing different autocorrelation function distribution characteristics of DFH signal and noise signal,test statistics are established.The dwell-ti... |
