摘　　要：根据红外烟幕的遮蔽原理,结合红外烟幕消光模型和扩散模型建立红外烟幕三维空间的透过率模型。针对传统烟幕遮蔽效果仿真方法的局限性,提出一种三维空间透过率的仿真方法,并对其进行数值计算与仿真验证。研究结果表明,探测器观察到的目标图像是多层透过率叠加的结果,遮蔽效果优于传统方法,对工程应用更具意义。According to infrared smokescreen＇s shielding principle,a model of infrared smokescreen transmittance in 3D space was constructed by using the extinction model and expanding model of infrared smokescreen .Considering the limitations of the traditional simulation method for the shielding effect of smoke screen,a method for simulating the transmittance in 3 D space was proposed,and simulation was made for the method.The result of research indicated that the images of target observed by the detector is the result of stacking of several layers of transmittance,and the shielding effect is better than that of traditional methods . The method is of great significance for engineering application .
