Abstract：Target tracking，recognition principle and typical anti-interference measures of infrared and radar composite seeker are analyzed，corresponding strategies and methods are put forward. Jamming mechanism of escort free-fight decoy and chaf to infrared and radar composite seeker is researched，interference models of escort free-fight decoy and chaff to infrared and radar composite seekerare established，and interference efectiveness isanalyzed.Analysis results show that it has good interference effect.

Key words：infrared and radar composite seeker;escort free-fight decoy and chaff；IR radiation; Doppler shift；interference effectiveness
