ALOS-2 and ALOS sample data is available from the following page. The Phased Array type L-band Synthetic Aperture Radar (PALSAR) is an active microwave sensor using L-band frequency to achieve cloud-free and day-and-night land observation. For more detailed information on the processing levels and file format, please refer to the following JAXA’s page. ( ALOS will provide global high spatial resolution earth observation data sets from three remote sensing instruments.

This improvement became possible by adding a “Spotlight mode” which enables the satellite to change its radio wave radiation direction to its moving … After five years of service, the satellite lost power and ceased communication with Earth, but remains in orbit.

In wide-area mode, image files are created for each scan. Raw data generated by every downlink segment and every band. The PALSAR-2 aboard ALOS-2 is an L-band Synthetic Aperture Radar (SAR) sensor, a microwave sensor that emits L-band radio waves and receives their reflection from the ground to acquire information. The continental U.S., Hawaii, and parts of Alaska are covered with 1⁄3 arc-second National Elevation …

PALSAR has a ScanSAR observation mode, with a swath (250-350 km) that is three to five times wider than conventional SAR images.

ALOS-2 will continue the L-band SAR observations of the ALOS PALSAR (Phased Array L-band Synthetic Aperture Radar) and will expand data utilization by enhancing its performance. It provides higher performance than theJERS-1's synthetic aperture radar (SAR). Global Partners : http://en.alos-pasco.com/list/.

ScanSAR wide beam (WB1, WB2) operates with a considerable loss of resolution. Advanced Land Observing Satellite (ALOS) is an advanced remote sensing satellite of the mission dedicated for the global high resolution earth observation, with compatibility of high resolution and wide swath width observation, and simultaneous observation of three-dimensional land topography, two-dimensional spectral images and geodetic land surface deformation.

Standard Products are designed for users who have advanced capability of image processing. Image quality-corrected (noise removed, dynamic range compressed) data from Level 1.5. The quality of an ALOS PALSAR RTC product is directly related to the quality of the digital elevation model (DEMs) used in the radiometric terrain correction (RTC) process. Vegetation; The table below summarizes the various DEM sources and the map indicates which DEM will be used in a given area. For inquires, please contact the following.

This is complex number data on the slant range following compression of the range and azimuth. ALOS-2,ALOS data and imagery is available for purchase. Copy right of images used in this website is as follows. ). Radiometric calibration and geometric correction coefficients are added for Level 1B processing. Launch. As one-look data, it includes phase information and will be the basis for later processing.

Progress from ALOS to ALOS-2 More wider, More precisely - Both resolution and observable area are greatly improved - 1）The resolution of the PALSAR was a maximum of 10 meters, but that of the PALSAR-2 has been improved to 1m to 3 meters. This paper introduces ALOS mission requirement and corresponding sensor specifications and further potential of data utilization.

The main specifications and product processing levels of PALSAR-2 are introduced here. Furthermore, observation data acquired by ALOS-3 is expected to be utilized in many fields not only to … Further information on ADEN zones can be found in this technical note.
