One of my classmates at Caltech did his PhD research by using a
modified WW2 tail-warning radar to measure the thickness of the ice in
various places. This was a small 400 MHz unit (couple of watts peak
power) working into a small Yagi antenna. They were able to get echoes
from the rock through over 5000 feet of ice. The operation was much
more of an adventure than planned, including a bent airplane they had to
fix by tieing a 2 x 4 to a wing strut, but he got his degree.
