摘要：

The radiation characteristics of a target change when a microstructured surface is used. Temperature and infrared (IR) radiation models are established for a flying spatial target with a microstructured surface. A simultaneous comparison was implemented for the temperature distribution and IR radiation characteristics of targets with normal and microstructured surfaces. This investigation was focused on the effects of detection angles on the IR radiation characteristics of a target with a microstructured surface. The results indicate that the utilization of a microstructured surface reduces the IR radiance of the spatial target, and a sudden change in the detection capacity was found for different detection angles, which is significant for the study of radiation characteristics of a target with a microstructured surface.
