Detection in low target to clutter ratio by massive multilooking. Application to the recovery of engine fragments buried in Greenland icesheet
International audience ONERA SAR system Sethi was involved in April 2018 in the search of engine fragments lost 6 months before by a jet-liner en route over Greenland and later buried under 2m of snow. Their radar echoes were thus attenuated by the propagation through snow and, because of the high b...
