Processing and Analysis of Radar Data to Map Layers Near the Bed to Determine Optimum Ice Core Site

We developed a very high sensitivity ultra-wideband radar operating at 200 MHz and optimized signal processor to map internal layers close to the bed. We used the radar to perform measurements with a large antenna array to collect data during the 2019–2020 field season in Antarctica. We processed and analyzed these data to generate detailed maps of internal layers to assist with selecting a drill site. The paper provides a brief summary of the radar system and field program. We also provide an overview of the algorithm, results, and their interpretation.
