To meet the simulation requirement for the intensity of infrared radiation and motion characteristics of target in the missile test, portable infrared target simulator using Cassegrain collimation optical principle is developed. The simulator utilizes Cassegrain collimator consisting of a parabolic primary mirror and hyperbolic secondary mirror as optical system, and uses blackbody as infrared radiation source. In cooperation with the adjustable diaphragm and rotary table, it can simulate radiation intensity and motion characteristics of infrared target. The experiments show that the focal length of the target simulator is 414. 8 mm, the system emergent light parallelism is less than 10″, the temperature range of the blackbody radiation is greater than 80℃, and it will be an effective way of testing angle motion of infrared seeker and infrared radiation energy strengths.
