摘要：
A recently developed 220GHz incoherent radar has the potential capability for remote sensing of low reflectivity atmosphere targets in Cloud Chamber. The stepped frequency system is used with a bandwidth of 10GHz. Preliminary reflectivity measurements of clouds for ranges between 0.2m similar to 4m in narrow Cloud Chamber. The instrument is briefly described. The uncertainties are highlighted 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 and sensitive system capable of providing accurate information for clouds.
