Radar depth sounding and imaging of deep glaciers in Antarctica and Greenland yield results for better understanding a changing climate and improving glacier modeling. A 15-element, airborne antenna array with an increased bandwidth was developed to advance the potential for radar measurements as part of NASA Operation IceBridge (OIB). These antennas were a(More)
— 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 30 MHz bandwidth. This instrument is capable of sounding a few-kilometer thick ice(More)
