Abstract:

Recently identification of individual radio transmitters is an important problem,which is different from traditional modulation identification of communication signals.Identification technology of radio transmitters is an analysis and extraction technology based on individual different signal dactylogram of the same kind of radio transmitters.The difficulties and solution are discussed in this article.The individual characters of steady radio signals,such as radio transmitters offset of carrier frequency and modulation parameter and the difference of signal hash export component,are discussed.These characters are carried as signal dactylogram reflecting the individual technical characteristic of radio transmitters.An identification project of individual radio transmitters is proposed which is important for individual identification to play a role in the military communication counter-measure program.

Key words: radio transmitters;pattern recognition;frequency stabilization;individual identification
