Operational parameters of airborne infrared decoy aerial-lauched set

IR decoy is one of the most common interferences for battleplane. The effect of IR decoy on the IR guidance air-to-air missile was closely related to control parameters of aerial-launched set. The main control parameters of aerial-launched set were determined by studying the process of IR countermeasure. The principle of centroid countermeasure of IR decoy was analyzed based on studying the characteristics of movement and IR radiation of self-defence plane , IR decoy and IR guidance missile. Control parameters model of aerial -launched set was built, including start and stop time of aerial -launched set, spacing of sequence aerial -launched decoy and dispensing number. The relationship between control parameters of aerial-launched set and interference effect was calculated. The test results prove that the model can improve the interference efficiency, and protect the self-defence plane.
