In order to solve the problem that the optic-electric detecting target board fails to work at nights or under low light level, it has studied the flying projectile’s properties of infrared radiation and the radiation attenuation properties of the flying projectile in the atmosphere. Through establishing the differential equations, the projectile’s surface temperature is obtained to calculate the flying projectile’s infrared radiation properties, according to atmosphere’s transmitting properties, the calculation method of atmospheric transmittance rate. The infrared radiation properties of three typical projectile are simulated by utilizing MATAB. The simulation result shows that the surface temperature of the flying projectile has a linear change with its velocity; the atmospheric transmittance rate is inversely proportional to the detection distance; Once the atmospheric attenuation factor is different, then the radiation energy received by the detector will be different.
