Phase-Sensitive Radio-Echo Sounding at the Devon Island Ice Cap, Canada
Abstract A radio-echo sounder has been built with which both the amplitude and phase of radio echoes can be measured. In experiments with this instrument at the Devon Island ice cap, in the Canadian Northern Territories, precise amplitude and phase measurements have been made upon radio echoes from...
