In order to explore the target recognition influence of the guidance through infrared radome under aer
odynamic heating, the straight through and the three way test methods were studied on the arc heated facility aimed at the simulation of heating and transmitting together. Several kinds of infrared radome material were tested under some aerodynamic heating conditions, and the infrared transmission effects were obtained. Between the two schemes, the three way test method is preferred due to its adaptability and convenience.
