Deep learning driven interpretation of Chang'E-4 Lunar Penetrating Radar

Icarus
We reprocessed Chang’E-4 Lunar Penetrating Radar data collected until 27th March 2023 with a total length of about 1440 m adding >400 m to the longest profile published so far. For data interpretation, we exploited a new Deep Learning-based algorithm to automatically extract reflectors from a processed radar dataset. The results are in terms of horizon
