摘　　要：红外诱饵弹是当前世界上最常用的红外对抗手段,它的红外辐射特性与其气动特性密切相关。为了描述气动特性对红外诱饵弹成像与非成像红外辐射性能的影响,首先应用流体力学与热传导理论,建立了红外诱饵弹的气动数学模型;其次从统计学的角度上提出了等效分子黑体假设,并运用概率论推导出一种计算热气体红外辐射特性的新方法;最后对红外诱饵弹气动辐射特性进行了仿真。仿真结果验证了所建模型的正确性。Infrared decoy has the most frequent application to infrared countermeasures in the world, and there is an immediate correlation between its aerodynamic characteristics and its infrared radiation characteristics. Mathematic models were built to describe the effect of aerodynamic characteristics on infrared imaging and unimaging. Firstly aerodynamic mathematic model of infrared decoy was built by applying the theories of hydromechanics and thermal conduction. Secondly equivalent molecule blackbody was proposed based on statistics, and a new calculation method for infrared radiation characteristics of hot gas was deduced by probability theory. Finally aerodynamic radiation characteristics of infrared decoy were simulated. The simulation results show correctness of the mathematic model.
