摘　　要：点面复合红外诱饵是国内外飞机平台使用的先进红外干扰装备之一,具备较好的对抗红外制导导弹的能力。为获得点面复合红外诱饵空中动态散布特性,为其使用提供理论基础,提升点面复合红外诱饵使用效能,对点面复合红外诱饵的点源诱饵和面源诱饵进行动力学和运动学分析,联立方程组并进行求解,获得了点源诱饵空中运动轨迹和面源诱饵在空中的散布情况,然后改变飞机平台速度进行仿真,获得了点源诱饵和面源诱饵的相对运动趋势和平台速度影响规律。基于点面复合红外诱饵空中动态散布特性仿真,开展使用研究,阐述了点面复合红外诱饵的干扰特性和干扰机理,干扰特性主要包括辐射强度值、辐射强度变化率和辐射面积,分析了点面复合红外诱饵在红外制导导弹导引头视场的形成特点,并基于此开展干扰机理研究,分析了点面复合红外诱饵在红外制导导弹的成像阶段和非成像阶段的干扰机理,能够为诱饵使用策略的制定提供参考和借鉴,提升飞机平台战场生存能力。Objective Point-surface composite infrared decoy is one of the advanced infrared jamming equipment used in aircraft platforms at home and abroad,which has a good capability against infrared guided missiles.For aircraft platforms,it is important to master the use strategy of point-surface composite infrared decoy.It determines the aircraft’s survivability during terminal defense.Currently,the use of infrared decoy lacks simulation analysis support,and there is a certain degree of blindness.With the improvement of couter-coutermeasure ability of infrared guided missiles,it brings higher requirements for the development and use of infrared decoy.Besides,there is a lack of simulation and research related to point-surface composite infrared decoy.So the airborne dynamic dispersion characteristics and application of point-surface composite infrared decoy is studied.Methods To obtain the dynamic walk characteristics of point-surface infrared decoy in the air,theoretical basis for its use is provided,and the effectiveness of point-surface infrared decoy is improved,dynamic and kinematic analysis of point source decoy and surface source decoy of point-surface infrared decoy(Fig.3)is performed,the simultaneous equations are solved,so the trajectory of point source decoy and dispersion of surface source decoy in the air were obtained.Then by changing the aircraft platform speed,the relative motion trend of the point source decoy and surface source decoy,and the influence law of the platform speed are obtained.Based on the simulation of airborne dynamic dispersion characteristics of point-surface infrared decoy,the use research is conducted,and the jamming characteristics and mechanism of the point-surface infrared decoy are described.Jamming characteristics mainly include radiation intensity value,rate of radiation intensity change and radiation area.The formation characteristics of point-surface infrared decoy in the field of view of infrared guided missiles are analyzed.And based on this,the mechanism research is carrie
