In winter, avalanches pose the biggest danger in the mountains. Avalanche monitoring is therefore of critical importance to ...

Until recently phased array radar has been very expensive, used only for military applications where the cost of survival weighs in the balance. With the advent of low-cost microwave devices and ...

For this purpose, both TanDEM-X and TerraSAR-X use an active antenna consisting of an array of transmit-and-receive modules designed for rapid changes in the direction of the radar beam as well as ...

However, smaller wavelengths have the advantage of being able to be projected in sharper beams by smaller antennas and generally have higher precision (Bruderer 1997). Radar has several benefits ...

the radar image will not show echos from precipitation that lies outside the radar's beam, either because the precipitation is too high above the radar, or because it is so close to the Earth's ...

DON'T MISS: The technology that can spot hidden tornadoes lurking in storms Modern weather radar works by sending a beam of microwave energy out into the atmosphere. These beams are angled ...

The estimated cost per plane: $143 million. Its curved edges scatter radar beams in different directions; horizontal tailfins enhance the F-22's signature maneuverability. Its afterburning ...
