In Microwave Staring Imaging, radar is located in a stationary platform and imaging the fixed area. It can realize continuous gaze and imaging of a specific area. The spatial-resolution of the traditional staring imaging, ie. the real-aperture imaging is limited by the actual antenna array aperture. A novel high spatial-resolution microwave staring imaging based on the temporal-spatial stochastic...
We detected glacier surge in West Kunlun Shan (WKS) located to the northern-western Tibetan plateau. We used several SAR archive data from 1990s and detected surface velocity field based on offset tracking with parallel flow assumption. We also used Landsat optical image from 1970s to detect terminus position of glaciers. Our results revealed velocity variation and terminus change caused by glacier...
ASNARO-2 is a small size Japanese earth observation satellite, which carries a newly developed X-band SAR mission system. Although the SAR mission system is light-weight and low cost system, its specification is not far behind from large satellite. It has the high resolution and wide swath. The performance of NESZ (Noise Equivalent Sigma Zero), which is less than the conventional high-spec satellite,...
Due to the global climate change, natural disasters are continuously threatening us all over the world. Today's high resolution, polarimetric and interferometric SAR system is the most powerful all-weather sensors for monitoring the earth environment and security territory under the severe weather environments. Korea is now ready for launching the first spaceborne SAR satellite, KOMPSAT-5, soon or...
TanDEM-X is a SAR mission with the goal to acquire a global digital elevation model of the Earth with an up to now unprecedented accuracy. This paper gives an overview on the actual status of the TanDEM-X mission in terms of acquisition strategy and planning of the third year of operation. The dedicated phases for the acquisition of Antarctica as well as for difficult terrain regions with shadow or...
TanDEM-X, a single-pass SAR interferometer with adjustable baselines in across- and in along-track directions was formed by adding a second, almost identical spacecraft to TerraSAR-X and flying the two satellites in a closely controlled formation. With typical across-track baselines of 150 to 500 m a global Digital Elevation Model with 2 m relative height accuracy at a 12-m posting is being generated...
During more than 20 years JAXA history on spaceborne and airborne SAR, L-band SAR has been adopted under the unique mission goal, i.e., the global observation. Over the JERS-1 SAR's essential findings on the surface deformation and the deforestation monitoring, both of which owe to the signal penetration of vegetation at L-band, ALOS has achieved the wider and more comprehensive global understanding...
Development of compact and low power consumption synthetic aperture radar (SAR) by Center for Environmental Remote Sensing (CEReS), Chiba University make it feasible to bring such payload in microsatellites. Under collaboration with Center of Satellite Technology, Indonesian Institute of Aeronautics and Space (LAPAN), the concept LAPAN-CHIBA microsatellite is being developed. The mission of the satellite...
With the relentless increase in population density, the anthropogenic expansion into natural terrestrial hazard zones has become irreversible resulting in ever more catastrophic disasters, not only in the Asia-Pacific region more so within the entire tropical belts engulfing Mother Earth. Thus not only the Indonesian-Pacific Islands, so also South America, Africa and back via the Indian Ocean Islands...
With the application requirement and technology development, the necessity and tendency of Synthetic Aperture Radar (SAR) imaging within the framework of multidimensional space joint-observation, which are polarimetry, frequency, angle, time series and etc., evoke catholic interests in SAR imaging research nowadays. Recent research progress on the Multidimensional Space Joint-observation SAR (MSJosSAR)...
