The development of IR dual-color combined guidance technology is presented. The operating principle of the IR dual-color guidance seeker is introduced. The anti-jamming technique of IR dual-color guidance is discussed. Several jamming techniques for IR dual-color guidance head are analyzed. These jamming techniques include special material decoy, stable flame pyrotechnic IR decoy, plasma gas aerogel, news pneumatic IR decoy and electro-optic countermeasure system.
