As the infrared homing technology is maturating day by day

it challenges the viability of the military target more than before. Based on the simulated results of surface temperature of target

the influence of the performance parameters( 、 、 ) of camouflage coating on the surface temperature of target and lock-on range of infrared detection system was analyzed. The analytical results show that all

and will affect the temperature of target and lock-on range

the surface temperature of target will rise as

are increscent and will reduce as the are increscent. For definite temperature of background and span of 、 、

the bigger and are

the bigger the lock-on range is

as the increases gradually

the lock-on range will firstly decrease and then increase. It is also discovered that there is an optimal emissivity to make lock-on range least. These results will be of great importance in the design

selection and application of infrared camouflage coating.
