We use a custom built, low-frequency, short-pulse, ground-based radar system to image deep (>100 m) internal layers and the base of the ice sheet.  Frequencies used with this system include 1, 2, 5 and 10 MHz. 

We also have a GSSI high-frequency (100MHz) ground-based radar system which can be used in several configurations and with a range of antennae frequencies.
