Images from focused synthetic aperture radar processing of echogram data with delay and sum antenna array processing, Greenland, 2016

To better understand processes affecting the ice sheets and to supply boundary condition information into ice sheet models and ice thickness for other ice sheet analysis, the Center for Remote Sensing of Ice Sheets (CReSIS) has designed, developed, and deployed a near high frequency (33-37 MHz) radar depth sounder in Greenland. An uninhabited aerial vehicle (UAV), dubbed the G1XB, was modified to carry this HF sounder. This dataset contains data collected at Russell Glacier in Greenland to demonstrate the system. This product uses focused synthetic aperture array (SAR) processing to improve resolution in along-track. This product is a pdf file for convenient browsing of the imagery. Files are named according to the format: /{$segment_id}.pdf. The segment ID is YYYYMMDD_SS where YYYY is the 4-digit year (e.g. 2011), MM is the 2-digit month from 1 to 12, DD is the 2-digit day of the month from 1 to 31, and SS is the segment number from 0 to 99. For example, “20080627_05.pdf” contains data from segment 05 taken on 2008-06-27. More information can be found in “Readme.pdf”.
