摘　　要：烟幕弹作为一种性价比高的装备广泛地应用在地面红外对抗领域。但在空空对抗领域,由于烟幕容易受到高速气流的影响,利用烟幕有效对抗空空红外制导导弹目前还是个难题。把载机、烟幕和导弹作为一个系统,将烟幕弹的发射时机、初始速度大小及方向与载机的规避相结合,利用相对运动的原理实现发射烟幕弹的精确定位,得出烟幕弹的发射方法;充分利用烟幕的遮蔽效应得出载机的机动规避轨迹,并反推出载机的控制率,得出载机的规避方法。从而解决了高速气流对烟幕的影响,得到了机载烟幕弹对红外制导导弹的干扰方法。通过对载机、烟幕、导弹复杂系统的红外对抗仿真,验证了这一干扰方法的可行性,并为机载红外干扰系统的设计及红外对抗战法的制定提供了参考。As a high performance -cost ratio equipment, IR screen is widely used in ground IR countermeasure field. But in air - to - air countermeasure aspect, it is difficult to interfere IR missile effectively with IR screen because of the impact of high speed airflow. The system including target war- craft, IR screen, IR missile is founded. The launching occasion, the original velocity, the orientation of IR screen and the target maneuver are combined together. According to the principle of relative movement, the accurate positioning of IR screen is realized and the launch method of the smoke bomb is obtained. By making full use of IR screen＇s shade effect, target＇s elusion trace is received, based which the target＇s control law is worked out, thereby target＇s elusion method is obtained. By this way, the influence of high speed airflow on IR screen is eliminated and a method of airborne IR screen interfering in IR missile is found. The simulation of the complex system including target, IR screen and missile shows that the interfering method is feasible, which offers a reference to the design of IR interfering system and the establishment of IR interfering tactic.
