InSAR datum connection using GNSS-augmented radar transponders

Multi-track Ps-insar: Datum Connection and Reliability Assessment

InSAR data acquired from independent overlapping tracks can be exploited for a reliability assessment of the Persistent Scatterer InSAR (PS-InSAR) technique. Here we present a mathematical framework for the datum connection of multiple tracks, simultaneously evaluating the precision and reliability of PS-InSAR estimates. This datum connection can be subdivided in two steps. Firstly, the PS loca...

2 Passive Radar using Transmissions by GNSS

Interferometric synthetic-aperture radar (InSAR)

Geodesists are, for the most part, a patient and hardworking lot. A day spent hiking to a distant peak, hours spent waiting for clouds to clear a lineof-sight between observation points, weeks spent moving methodically along a level line – such is the normal pulse of the geodetic profession. The fruits of such labors are all the more precious because they are so scarce. A good day spent with an...

Augmented Reality Using Ultra-Wideband Radar Imagery

The U.S. Army Research Laboratory (ARL) has been investigating the utility of ultra-wideband (UWB) synthetic aperture radar (SAR) technology for detecting concealed targets in various applications. We have designed and built a vehicle-based, low-frequency UWB SAR radar for proof-of-concept demonstration in detecting obstacles for autonomous navigation, detecting concealed targets (mines, etc.),...

On the Future of Radar Altimeter Calibration Using Gnss Buoys

The environmental satellite ENVISAT was successfully launched by the European Space Agency ESA in March 2002. An elaborate field campaign was conducted in the Mediterranean Sea near the coast of Menorca Island in order to recover the altimeter’s bias using high sea GPS buoys. After a brief presentation of this campaign including major results for the sea surface heights, a number of questions r...
