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.
