摘　　要：面源型红外诱饵对红外成像制导空-空导弹具有较好的干扰效果。本文通过分析红外诱饵对红外成像制导空-空导弹的矩心干扰机理,建立了包括飞机-导弹的运动轨迹、飞机红外辐射模型以及红外诱饵弹和矩心的运动轨迹方程在内的红外诱饵-导弹对抗模型,研究了红外诱饵对红外成像制导空-空导弹的干扰效果,最后通过算例分析矩心运动轨迹,计算了在不同投放时间间隔和投放数目下飞机被击中的概率。Surface-type infrared decoy has a good jamming effectiveness to infrared imaging guided air-to-air missles. In this paper, the centroid jamming mechanism of infrared decoy against infrared imaging guided air-to-air missles is analyzed. An infrared decoy-missile countermeasure model including aircraft-missile trochoid, aircraft infrared radiation and trochoid equation of infrared decoy is established. The jamming effectiveness of infrared decoy against infrared imaging guided air-to-air missles is studied. Finally, the propability of the aircraft to be hitted in different decoy interval and different decoy quantity is analyzed by calculating the examples of centroid trochoid.
