  • Abstract:  Abstract Interferom etric SAR (InSAR) has become an effective way of measuring objects in three dimensions and carrying out terrain survey for both civil and military applications. In this regard InSAR simulations provide synthetic data to test and validate the process of InSAR applications. The simulations for InSAR for both airborne and space borne InSAR applications generally fall in two categories. First type includes SAR raw data generation based on the backscatter model of the land surface combined with the SAR pulse transformation function and the second type is to simulate the interferogram, based on a digital elevation model (DEM). The aim of this paper is to develop an interferogram simulation using techniques which are easy to use and grasp. After the interferogram formation further InSAR processes are simulated to generate height maps and perform geo-coding

            • Sentinel system pictures Napa quake
              First report from Europe's new quake-watcher
            • Sentinel-1 poised to monitor motion
              Sentinel-1A's radar acquired the two images that make up this interferogram in its 'Interferometric wide Swath' mode on 9 and 21 August 2014 over Sicily, Italy. The rainbow-coloured fringes mainly denote differences in topography - hence the steep slopes of Mount Etna can be seen clearly.
            • Radar Images Used To Map Napa Valley Earthquake
              ESA Sentinel-1 A has added yet another string to its bow. Radar images from this fledgling satellite have been used to map the rupture caused by the biggest earthquake that has shaken northern California in 25 years. Scientists collaborating through the UK Natural Environment Research Council’s Centre for the Observation and Modelling of Earthquakes, Volcanoes and Tectonics ( COMET ), used ...
            • The psychedelic image from space that reveals just how big the Napa earthquake really was
              Radar images from the Sentinel-1A satellite have been used to map the biggest earthquake that has shaken northern California in 25 years.
            • How the Napa Quake Deformed Earth (Satellite Photo)
              The 6.0-magnitude earthquake that rocked California's Napa Valley last month not only injured dozens of people and caused millions of dollars in damage, but it also warped the surface of Earth. Observations from the European Space Agency's (ESA) new Sentinel-1A satellite reveal changes on the surface through a technique known as synthetic aperture radar interferometry. Ground deformation leads ...
            • New satellite can map earthquakes
              Throughout human history we've been terrified by the forces beneath our feet. Earthquakes and volcanoes used to be seen as incomprehensible acts of God, but even today - despite improved monitoring - they remain frighteningly unpredictable.
            • Radar Eyes Can See the Scars of the Napa Valley Quake From Space
              The colourful picture you're looking at isn't modern art. In fact, it's a radar image that shows the damage caused by the earthquake that hit California's Napa Valley at the end of last month. Read more...

              A European satellite mapped how the Napa quake ruptured the Earth's surface using a technique that highlights minute surface changes in psychedelic colors. However, the maps, known as interferograms, will never replace fieldwork, geologists said. See also: Drone Shows Napa Quake's Impact From Above The interferograms were made with data from Sentinel-1A, the first satellite in the European Space ...

              Alan Buis, NASA's Jet Propulsion Laboratory NASA data and expertise are proving invaluable in California’s ongoing response to the Aug. 24 magnitude 6.0 earthquake in Napa Valley , northeast of San Francisco. The quake was the strongest to occur in the San Francisco Bay Area in a quarter-century and caused significant regional damage. [ Watch the Video: NASA Radar Data Reveals Fault Movement ...
