| Abstract: | PN code capture is a difficult problem in radio reconnaissance and navigation warfare.With the demand of such field as communication reconnaissance,comb filter's application to capture of short cycle PN-code under self-jamming cartier is studied. Based on its periodicity,it is proved that the capture of unknown structure PN code can be realized in enough short time using comb fil- ter,which is simple in calculation and easy to carry out. |
