Latest Synthetic aperture radar Stories
The detection and recognition of an object with small RCS, such as a stealth target, is the most difficult problem to solve for the modern radar system.
As our quest for knowledge about our planet grows, so does the need for novel technologies to offer new insight into the changing face of Earth. Researchers are excited about the potential of a new radar wavelength to image Earth from space.
Archived radar data from the Envisat mission are playing an important role in mapping landslides in Switzerland.
NASA software that models the behavior of earthquake faults to improve earthquake forecasting and our understanding of earthquake processes, and NASA's first mobile application are co-winners of NASA's 2012 Software of the Year Award.
The loss of the Envisat satellite is affecting services by Europe’s Global Monitoring for Environment and Security program. Efforts are being coordinated with other space agencies to fill some of the gaps, but the situation adds further urgency to launch the Sentinel missions.
The importance of global and frequent data coverage of volcanoes was highlighted in a recent article published in Science. Satellites are finding that volcanoes previously thought to be dormant are showing signs of unrest.
Recent studies show that satellite radar data can be exploited to map forest height, 3D forest structure and their natural or anthropogenic disturbance with high spatial resolution and accuracy.
In the early hours of 1 March 2002, the largest Earth observation satellite ever built soared into orbit from ESA’s launch base in Kourou, French Guiana. For a decade, Envisat has been keeping watch over our planet.
Endeavour launched from Kennedy Space Center on April 9. 1994 at 7:05 AM EDT and landed at Edwards AFB on April 20 at 9:54 AM PDT. The shuttle orbited 183 times at an altitude of 121 nautical miles at an inclination of 57 degrees and travelled 4.7 million miles. The mission lasted 11 days, 5 hours, 49 minutes, and 30 seconds. The primary payload was the Space Radar Laboratory (SRL-1), located in payload bay; activated by crew and operated by teams on ground. SRL-1 included the Spaceborne...
