Impact of spatial averaging on radar reflectivity at internal snowpack layer boundaries
Journal of Glaciology, 2016 Microwave radar amplitude within a snowpack can be strongly influenced by spatial variability of internal layer boundaries. We quantify the impact of spatial averaging of snow stratigraphy and physical snowpack properties on surface scattering from near ...

Measuring currents, ice drift, and waves from space: the Sea surface KInematics Multiscale monitoring (SKIM) concept [PDF]
Ocean Science, 2018 We propose a satellite mission that uses a near-nadir Ka-band Doppler radar to measure surface currents, ice drift and ocean waves at spatial scales of 40 km and more, with snapshots at least every day for latitudes 75 to 82°, and every few days for ...

Effects of Temporal Sampling Interval on the Moon-Based Earth Observation Geometry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 The effects of temporal sampling interval on the moon-based earth observation geometry are analyzed in this study based on three observation angles, namely viewing zenith angle, solar zenith angle, and relative azimuth angle. According to the definitions

Overlap Correction Function For an Airborne Based Lidar
EPJ Web of Conferences, 2016 The present research envisages the estimation of the overlap correction function for an airborne nadir-mounted lidar using multi-angle measurements. We have scanned a series of offnadir angles and after data processing we have been able to determine the ...
