N2 - We have developed improved versions of three different radar systems and integrated them as an airborne instrumentation suite for sounding and imaging Polar ice sheets. The first instrument consists of a multi-channel, coherent, pulsed radar operating at VHF with up to 20 MHz bandwidth. This instrument is capable of sounding a few-kilometer thick ice while flying at altitudes up to 10 km above mean sea level. The second instrument is designed to operate at UHF using a burst of narrow-bandwidth signals to digitally synthesize a bandwidth of in excess of 300 MHz. This apparatus is used to measure internal layers of the ice sheet to a depth close to 100 m. The third component to the instrumentation package is based on a frequency-modulated continuous wave (FMCW) radar, which operates at microwave (Ku band) frequencies with up to 1 GHz of instantaneous bandwidth. This radar set is used to measure the ice sheet surface elevation profile with centimeter accuracy. We are presenting a description of each system, with emphasis on the VHF depth sounder. We also present sample field test results obtained during the 2009 austral summer season in Antarctica, as a validation of the performance of the instrument package.
