摘　　要：分析红外诱饵弹的干扰原理,并建立红外诱饵弹模型;考虑红外导弹的跟踪、控制、运动学等环节,建立导弹制导回路模型;在导弹制导飞行过程中,分析诱饵和飞机与跟踪器视线的位置关系,确定红外中心的位置和速度。按时间进行典型诱饵弹干扰情景下的三维飞行模拟,从而分析诱饵弹多组间隔发射情形下,导弹脱靶量与诱饵强度、发射速度、发射间隔的关系。算例验证了方法的有效性、合理性。The characteristic of airborne infrared decoy is analyzed, and the model of infrared decoy is built. The mathematical model of missile guidance loop is developed, based on the models of tracking system, guidance and control system, missile kinematics equation, and so on. In the navigation flight of the missile, the geometry among the decoy, the aircraft, and the tracker is analyzed to determine the location and velocity of the infrared centroid. The three-dimensional flight simulation is accomplished under classic encounter scenarios. Consequently, the miss distance distribution due to decoy intensity, launch velocity, and launch interval is derived when the aircraft is deploying many groups of decoys at intervals. The example and results show that the method is effective and reasonable.
