With the establishmentof the equivalent medium model, RTM-DRE was applied to study radiative transfer intransparent medium with scattering particles. By taking into account of absorption andscatter of particles, absorption of binder and reflection of interface, the apparent spectrumabsorption model of thermal control coatings was developed by RTM-DRE combined withMies theory. Validity, computational error and time of the model were validated andanalyzed. Furthermore, the apparent spectrum absorption characteristics of thermal controlcoatings were studied, and the influences of optical characteristics of binder and particles,volume fraction of particles, particles diameter, characteristics of interface, and incidentangle of irradiance were analyzed.
