The development of radar systems operating at G-band (110–300 GHz) with small size, weight, and power requirements can offer new possibilities for probing clouds and precipitation from space and lead to novel mission concepts. To advance the technology needed to achieve such objective, a ground-based G-band Doppler radar prototype for atmospheric profiling has been developed and demonstrated with different targets. This article describes the radar architecture and discusses the instrument calibration and reflectivity and Doppler velocity measurements of clouds and precipitation.
