Abstract
The advantage ofusing high-energy pulses makes classical pulse radar the favoured system for surveying very thick glaciers compared to other radar techniques. A high vertical resolution is necessary when using groundpenetrating radar for near-surface investigations at a depth range down to 50 m, like permafrost or internal layering in glaciers. Stepped-frequency radar technology offers an attractive alternative to the classical pulse radar systems. In order to compare the performances of stepped frequency instruments with a 150 MHz pulse radar during an airborne survey, both systems were used over the same area during a test flight for an ice thickness survey. The possibilities and limitations of the pulse radar and steppedfrequency technology are discussed with special emphasise on near-surface airborne investigations. Starting with theoretical considerations, an overview of the measurement campaign is presented, results are discussed, and conclusions are drawn.
