Smoke screen jamming is an important passive jamming method,which plays an important role in countering infrared imaging guidance weapons.In view of the lack of research on the influence of smoke screen jamming on the hit probability of infrared imaging guided missile,a method of calculating the hit probability of smoke screen interference is proposed.The smoke screen jamming model is present,the smoke screen transmittance is analyzed,the smoke screen jamming test is introduced,and the conclusion that smoke screen can effectively jamming infrared imaging guidance system is obtained.The calculation formula of hit probability of infrared imaging guidance system under smoke screen jamming is deduced.The simulation results show that the hit probability of infrared imaging guidance system under smoke screen jamming is greatly influenced by smoke screen concentration,smoke screen thickness,tracking accuracy and attack distance.
