Polar Radar for Ice Sheet Measurements \| PRISM Updates

PRISM Updates: Radar Team: Important Aspects of the PRISM Radar

What is Special About This Radar

Using radar to map the bedrock under polar ice poses special challenges.
The radar creates a reflectivity map of the bedrock and the condition of the ice near the bedrock.
The radar is unique because it will map large areas of the bedrock.

Challenges The Radar Team Must Address

The radar signal will be distorted due to refraction.
The radar signal will be weaker in ice than in air.
A mirror-like (specular) wet bedrock surface limits the radar reflectivity in areas of ice streams and glaciers.
