High Resolution Ice Thickness and Plane Wave Mapping of Ice Sheet Near-Surface Layers
Entry ID: Kanagaratnam_0230378

[ Update this Record ]

Summary
Abstract: This award supports a project to build and test a 12-18 GHz radar system with a
plane wave antenna. This is a wideband radar operating over a frequency range
of 12 to 18 GHz to detect near-surface internal firn layers of the ice sheet
with better than 10 cm resolution to a depth of approximately 7 m. These
measurements will allow determination of spatially continuous snow ... View entire text

Description: Scientists and engineers at the University of Kansas are applying their
expertise to develop and utilize innovative radar and robotic rovers to measure
ice thickness and determine bedrock conditions below the ice sheets in
Greenland and Antarctica. They are doing this through the auspices of a grant
from the National Science Foundation (NSF) and NASA. This grant has been named
PRISM (Polar Radar for Ice Sheet Measurements).
