摘　　要：机载红外诱饵投放后的运动轨迹,以及与载机的分离过程是红外对抗研究中的重要内容。文章首先分析了机载红外诱饵投放后的运动特征,建立了诱饵运动数学模型,使用四阶龙格-库塔方法求解方程;通过坐标转换得到目标-诱饵在导引头视场中的分离形态,分别使用Matlab、MOS电阻阵进行了数字和半实物仿真,结果表明仿真过程较为逼真地模拟了目标-诱饵的分离轨迹。最后结合仿真结果,阐述了导引头视场中目标-诱饵分离过程的影响因素,并对运动特征下的机载红外诱饵干扰与对抗进行了分析。The moving track of airborne infrared decoy and the separation process from the carrier, are important contents in the research of infrared countermeasure. Firstly, the motion characteristics of airborne infrared decoy are analyzed, and a mathematical model of the decoy motion is established. Through coordinate transformation, the separation process of a target and a decoy is mapped into the seeker field of view. The digital and hardware in the loop simulation of MATLAB and MOS resistor array are carried out respectively. The results show that the actual separation process of a decoy can be simulated more realistically. Finally, the influence factors of target-decoy separation process in seeker field of view are illustrated, and the jamming and countermeasure of airborne infrared decoy are analyzed under the motion characteristics.
