摘　　要：This paper presented an idea for the average brightness temperature of lossless antenna aperture, gave its expression for matched and dismatched noise source. This expression showed that the average brightness temperature of antenna aperture related with three factors: the noise temperature of noise source, the reflection coefficient of noise source, and the aperture efficiency.This paper presented an idea for the average brightness temperature of lossless antenna aperture, gave its expression for matched and dismatched noise source.
