Subsurface Imaging using Ground-Penetrating Radar Measurements
Much work has been done toward reconstructing the electrical parameters of an unknown buried object. Many methods, and accompanying results from simulations, have been presented. Most research in the area, however, has been in developing imaging algorithms that have been tested primarily through computer simulation. This paper presents a newly constructed facility for ground-penetrating radar e...
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 کاملSpaceborne 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 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 کاملCompressive sensing for subsurface imaging using ground penetrating radar
The theory of compressive sensing (CS) enables the reconstruction of sparse signals from a small set of non-adaptive linear measurements by solving a convex ‘1 minimization problem. This paper presents a novel data acquisition system for wideband synthetic aperture imaging based on CS by exploiting sparseness of pointlike targets in the image space. Instead of measuring sensor returns by sampli...
