Radio Echo-Sounding of Riiser-Larsenisen (Abstract only)

Radio Echo Sounding of the Greenland Inland Ice

Radio echo sounding has been used for a number of years in the exploration of polar ice such as the inland ice in Greenland and Antarc­ tica. By means of this technique a number of important glaciological and geophysical parameters may be deter­ mined. Examples are ice thickness, bedrock topography and structure, stratification patterns which are used for climate and flow patterns studies, and ...

Instrwnents and Methods Miniature high-power illlpulse transmitter for radio-echo sounding

We have developed a miniature high-power impulse transmitter for radio-echo sounding of glaciers. It features two synchronous second break-down pulse generators operating in a differential configuration. Specifications include bipolar 550 V pulses having rise times less than 2 ns, 512 Hz repetition rate, 180 mA at 10-14 V d.c. operating power, 5 mA standby current and maximum dimension of 12 cm...

Atmosphere sounding using GPS radio occultation

Introduction On July 17, 1995 the U.S. Air Force announced “ .. that today the Global Positioning System (GPS) satellite constellation has met all requirements for Full Operational Capability”. Apart from precise positioning GPS signals also can be used to derive characteristic properties of the propagation medium (neutral atmosphere and ionosphere). Onboard the Low-Earth-Orbiting MICROLAB-1 sa...

RF Sounding: Generating Sounds from Radio Frequencies

On the other hand the problem of the electromagnetic pollution has recently become an important theme of discussion for both scientific and media communities and it has often been faced with incomplete, where not wrong, knowledge of the phenomena involved. This is especially true while concerning with cellular networks where the most popular belief is that transmitting antenna produce the most ...
