Detection Technology of Clover-2000 HF Communication Protocol Signals
摘要
Abstract
The rapid detection of specified protocol signals is an important task in spectrum monitoring field.In view of broadband detection of Clover⁃2000 protocol signals in HF spectrum monitoring,this paper proposes a detection technology of Clover⁃2000 protocol signals based on spectrum template matching and instantaneous spectral autocorrelation. Firstly, the standard spectrum template is constructed according to the second Clover⁃2000 protocol,and then the maxhold spectrum of the input signal is calculated,after that the set of correlation coefficient between the template and the sliding maxhold spectrum is computed to realize the preliminary detection of the Clover⁃2000 signals. To separate Clover⁃2000 signal from 2GALE, the instantaneous spectral autocorrelation is used. Finally, the effectiveness of this algorithm is proved by simulations and practical data.关键词
