Second-Generation Spaceborne Precipitation Radar

چکیده
The Global Precipitation Mission is currently being planned as a follow-on to the Tropical Rainfall Measuring Mission. One of the key components of the GPM science instrumentation is an advanced, dual-frequency rain mapping radar. In this paper, we present a potential system concept for this secondgeneration spaceborne precipitation radar. This proposed design ncorporates s veral advanced features, including 13.6/35-GHz dual frequency radar channels; a dual-frequency, wide-swath scanning, deployable antenna; digital chirp generation and the corresponding on-board pulse compression scheme; and adaptively antenna scanning.

Spaceborne Atmospheric Radar Technology
NASA is developing advanced instrument concepts and technologies for future spaceborne atmospheric radars, with the over-arching objectives of making such instruments more capable in supporting future science needs, and more cost effective. Two such examples are the Second-Generation Precipitation Radar (PR-2) and the Nexrad-In-Space (NIS). PR2 is a 14/35-GHz dual-frequency rain radar with a de...
متن کاملIntercomparison of Vertical Structure of Storms Revealed by Ground-Based (NMQ) and Spaceborne Radars (CloudSat-CPR and TRMM-PR)
Spaceborne radars provide great opportunities to investigate the vertical structure of clouds and precipitation. Two typical spaceborne radars for such a study are the W-band Cloud Profiling Radar (CPR) and Ku-band Precipitation Radar (PR), which are onboard NASA's CloudSat and TRMM satellites, respectively. Compared to S-band ground-based radars, they have distinct scattering characteristics f...
