Paper Abstract

A recently developed 220GHz incoherent radar has potential for remote sensing of low reflectivity atmosphere targets in Cloud Chamber. Stepped frequency system is used and bandwidth 10GHz. Preliminary reflectivity measurements of clouds for ranges between 0.2m~4m in narrow Cloud Chamber. The instrument is briefly described. Highlighting uncertainties due to highly variable attenuation and signal interference. Then the results of investigations of the transmitter, receiver, Antennas, as well as the atmospheric Propagation Effects are presented. The results of this effort demonstrate that the radar is a stable, sensitive, system capable of providing accurate power for clouds.
