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...
This paper conducts the research to the 3 mm wave band millimeter-wave active passive compound detection system signal examination and processing, major study on the design and methods of the system based on TMS320LF2812 signal processor, including the signal analysis and processing of millimeter-wave radar and radiometer. Some practical ways has been improved on hardware and software in AD sampling,...
