A super-resolution laser altimetry concept

SPIE Proceedings, 2011
A super-resolution laser altimetry technique has been proposed to provide improved lidar altimetry from Cloud Aerosol Lidar and Infrared Pathfinder Satellite Observation(CALIPSO) lidar data, and it is applicable to other similar atmospheric profiling lidar with low-pass filters.

ICESat Full-Waveform Altimetry Compared to Airborne Laser Scanning Altimetry Over The Netherlands

IEEE Transactions on Geoscience and Remote Sensing, 2009
Since 2003, the full-waveform laser altimetry system onboard NASA's Ice, Cloud and land Elevation Satellite (ICESat) has acquired a worldwide elevation database. ICESat data are widely applied for change detection of ice sheet mass balance, forest structure estimation, and digital terrain model generation of remote areas.

Testing of Airborne Laser Altimetry Sensors

2018 5th IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2018
This paper synthesizes the results of the mechanical shock, vibration and temperature tests that have been executed in order to verify the performance characteristics of the device under test (D UT) in environmental conditions representative of those which may be encountered during the operation of the equipment.

The ICESat-2 Laser Altimetry Mission

Proceedings of the IEEE, 2010
Satellite and aircraft observations have revealed that remarkable changes in the Earth's polar ice cover have occurred in the last decade. The impacts of these changes, which include dramatic ice loss from ice sheets and rapid declines in Arctic sea ice, could be quite large in terms of sea level rise and global climate.
