Design, development, and measurement capabilities of novel, airborne pod-based millimeter wavelength radar is described. The millimeter wavelength radar frequency of operation is 94 GHz (3 mm wavelength). The radar has been designed to fly on the NCAR Gulfstream V HIAPER aircraft and is called HIAPER Cloud Radar (HCR). The pod-based configuration occupies minimum cabin space and maximizes scan coverage. The radar system design and its expected performance, as well as techniques for calibrating reflectivity and correcting Doppler velocity for aircraft attitude and motion, are described.
The capability of HCR is enhanced by the coordination with High-Spectral Resolution Lidar (HSRL). The lidar, designed and built by the University of Wisconsin, provides unique measurements
of both backscatter and extinction. The HCR measurements and coincident HCR and HSRL measurements are analyzed for their utility to estimate liquid water content (LWC) and mean particle size. Retrievals of LWC and mean particle sizes from remote radar and lidar measurements are shown.
