摘要

介绍了利用扩频滑动相关系统对干湿混凝土墙体进行UHF信号反射测量的结果。较大比例的入射功率被湿壁面反射，由于受潮引起的反射系数变化约为10%。讨论了在实际壁厚、介电常数和入射角条件下反射系数的变化规律。

Moisture effects on the penetration loss through exterior building walls

Results of UHF signal reflection measurement performed with dry and wet concrete walls using a spread spectrum sliding correlation system are presented. Larger proportions of incident power were reflected from the wet wall, and the change induced in the reflection coefficient due to moisture was approximately 10%. The reflection coefficient behavior under practical values of wall thickness, permittivity and incidence angle is discussed.
