G-Band Radar for Humidity and Cloud Remote Sensing [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2021
VIPR (vapor in-cloud profiling radar) is a tunable G-band radar designed for humidity and cloud remote sensing. VIPR uses all-solid-state components and operates in a frequency-modulated continuous-wave (FMCW) radar mode, offering a transmit power of 200–300 mW.
