摘　　要：针对外场烟幕性能测试受气象条件和环境因素的影响较大,对准确评估抗红外烟幕遮蔽性能存在较大困难的情况,结合气象条件从烟幕透过率的变化引起导引头信噪比变化的角度,建立了烟幕干扰效果的评估模型,通过计算机仿真,结合大气透过率、风速、地面粗糙度等因素得出了烟幕对红外制导导弹的干扰效果。Aiming at the property testing of smoke screen is deeply affected by weather and environment, it is difficult to estimate property of anti-IR smoke screen exactly, the jamming effict estimating model of the smoke screen is established based on analyzing the process of smoke screen anti-IR guided missile. The model is discussed from the point of SNR of missile influenced by transmittance of smoke screen, and jamming effict of the smoke screen against IR guided missile is simulated by numerical computation.
