Development of Frequency Hopping Technology and Jamming Countermeasure

Communication jamming and counter-jamming are the kernel of communication countermeasure and counter-countermeasure.Frequency hopping(FH) communication is the most effective technology widely used in shortwave communication jamming and counter-jamming . Its features determine its strong ability of counter-jamming. So it is specially important to jam the FH communication. Barrage jamming or track jamming can be used to the FH target. The paper introduces the principle,feature,key technology and developing direction of FH technology in communication countermeasure. It is emphasizely discussed on how to jam the targets which employ FH communication.
