The next day we drove out to Stanley, Idaho, to test our equipment on the snow. Unsurprisingly, it is extremely difficult to simulate conditions of the Greenland Ice Sheet during April in Idaho, but we enjoyed the warm weather and sunshine during out testing. We assembled the 100 MHz and 500 MHz systems in a train of sleds behind two snowmobiles and attached the FMCW system to a third.

After a few hours of plugging in various cables, setting up the GPS, zip-tie-ing pieces of equipment to the sleds, and determining how exactly to drag everything behind a snowmobile, we were able to actually test our equipment. Since the systems are very fragile, we had to start our tests at a very low speed and gradually speed up to determine how fast we can drive without rattling the radar too much. Additionally, the computer takes a while to process all the incoming data, so our speed on the ice sheet will be limited by the number of antennas we are dragging and the precision of data we want to acquire.
