介绍了一种空天平台红外探测巡航导弹的建模仿真方法。首先全面分析了巡航导弹的作战特点和红外辐射特性，然后综合考虑了海拔高度、斜程传输路径、大气吸收、散射和天气等因素，建立了红外传输路径大气透过率的计算模型；在考虑地球曲率的条件下给出了空天平台探测巡航导弹的距离模型和分析方法；最后通过仿真对比了天基、临空和空基3类探测平台探测巡航导弹目标的能力特点，给出了相关结论，验证了该方法的有效性。%A modeling and simulation method for air-space platform infrared detection against cruise missile is introduced. Firstly, cruise missile’s operational traits and infrared radiation characteristics are analyzed completely. And then with which altitude, slantwise route, atmosphere absorption, atmosphere dispersion and weather factor, etc are taken into consideration, the atmospheric transmission model is proposed. The detecting-distance model and its analysis method are given out with earth curvature taken into account. At last, the abilities of three kinds of detection platform of space-based, near-space-based and air-based against cruise missile are analyzed and contrasted by simulation and some relative conclusions are presented, which validated the method’s validity.
