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 کاملSpaceborne Imaging Radar Research in the 1990s: an Overview
The imaging radar experiments on Seasat (1978) and on the space shuttles (SIR-A in 1981 and SIR-B in 1984) have resulted in wide interest in the use of spaceborne imaging radars in earth and planetary sciences. The radar sensors provide unique and complementary information about what is acquired with visible and infrared imagers, including subsurface imaging in arid regions,I ,2 allweather obse...
متن کاملSecond-Generation Spaceborne Precipitation Radar
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 featu...
متن کاملSpaceborne Radar Technologies for Earth Remote Sensing
Synthetic Aperture Radar (SAR) is an indispensable source of information in earth observation since SAR is the only spaceborne sensor that has highresolution, all-weather and day-and-night imaging capability. Within the next 10 years more than 20 spaceborne SAR systems from different nations will be launched. Increased demand for larger swath width and higher geometric resolution poses contract...
متن کاملSpaceborne Laser Altimeter Instrument Parameter Calibration
To take advantage of the unique observing capabilities of lidar technology, two NASA dedicated Earth observing laser altimeter missions are scheduled for launch in the near future: the Vegetation Canopy Lidar (VCL) and the Ice, Cloud and land Elevation Satellite (ICESat). To properly geolocate the surface returns it will be necessary to verify and calibrate pointing, ranging, timing and orbit p...
