Observing glacier elevation changes from spaceborne optical and radar sensors – an inter-comparison experiment using ASTER and TanDEM-X data [PDF]

The Cryosphere
Observations of glacier mass changes are key to understanding the response of glaciers to climate change and related impacts, such as regional runoff, ecosystem changes, and global sea level rise.

Doppler compensation in forward-looking STAP radar

, 2022
S.253-258For air- and spaceborne MTI radar the clutter Doppler frequency depends on range for all array geometries other than linear sidelooking. This applies particularly to forward-looking arrays.

Physically comprehensive representation of Bragg facet Doppler velocity for wave-induced bias correction in SAR ocean surface currents retrieval

Journal of Ocean Engineering and Science
The direct measurement of radial ocean surface currents (OSC) using SAR remains a major challenge due to wave-induced bias (WB). The bias caused by ocean waves arises from both the inherent motion of the scattering facets and the modulation of these ...
