Abstract: Back reflection characteristics of laser were researched for the infrared camouflage coating and the microwave absorbing coating. The results show that the back reflection of laser decreases with the increasing of the emissivity of coating. Considering the application to a tactical target, the laser and infrared camouflage can be compatible by the reasonable design of the coating pattern. Considering the camouflage principle and material design, the laser and microwave absorption can be compatible by making a microporous surface on the material, which makes back reflection of laser decrease sharply and microwave absorption change hardly.
