Abstract
In the sub-millimeter wave propagation process, attenuation is mainly due to the effects of atmospheric particles, such as water vapor. It’s also caused by absorption and scattering by hydrometeors. This paper focuses on the effects of hydrometeors on sub-millimeter wave propagation. The formula for calculating the attenuation cross-section of raindrops is given, as well as the distance formula of sub-millimeter wave radiometers. Finally, this paper mentions the effects of some weather phenomena on detection distance of sub-millimeter wave radiometers. Taking cloud attenuation as an example, the relation between distance and temperature or moisture content is analyzed.
