Pol-InSAR Results from ALOS-PalSAR

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
The launch of JAXA's ALOS in January 2006 provides - for the fist time since the SIR-C/X-SAR mission's in the 80's - the opportunity to acquire Pol-InSAR data from space. Indeed, PalSAR (i.e. the SAR instrument onboard of ALOS) is able to operate in a quad-pol mode - declared by JAXA as an "experimental mode" - that allows the acquisition of Pol-InSAR ...

A Structural Classification of Australian Vegetation Using ICESat/GLAS, ALOS PALSAR, and Landsat Sensor Data

Remote Sensing, 2019
Australia has historically used structural descriptors of height and cover to characterize, differentiate, and map the distribution of woody vegetation across the continent but no national satellite-based structural classification has been available.

Deformation monitoring using the ALOS/PALSAR

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Because of the higher interferometric coherence, ALOS/PALSAR data are often used for monitoring the deformation caused by the disaster events (i.e., earthquakes, volcanoes, land subsidence by water and oil pumping, land slide, etc) using the interferometric data analysis.

Flood disaster monitoring with ALOS/PALSAR observation

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
We investigate an effective algorithm to identify flood-inundated area with ALOS/PALSAR observations. Radar cross section from water surface is generally smaller than that from ground surface without water, which derives larger differences of radar cross section in flood-inundated area because there is no water in this area before disaster.

Study of environmental issues with ALOS PALSAR data

IEEE International Geoscience and Remote Sensing Symposium, 2003
The Advanced Land Observing Satellite (ALOS) will carry three advanced sensors for addressing many environmental issues, such as vegetation change, water resource management, disaster and earthquake mitigation, and cryosphere monitoring, in a broad range of earth science disciplines.

ALOS PALSAR Calibration and Validation Results from Sweden

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
In 2006 calibration activities for ALOS PALSAR were conducted in Sweden. Four five-metre trihedral corner reflectors and three smaller dihedral reflectors were deployed and operated during eight months. 23 PALSAR scenes were acquired over the calibration site allowing an evaluation of the quality and temporal stability of the data.

Hardware Performance of PALSAR-3 Onboard ALOS-4

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The paper describes hardware performances of PALSAR-3 onboard ALOS-4, which is a follow-on mission of ALOS-2. To implement land deformation and subsidence monitoring with SAR interferometry and to improve performance of disaster monitoring (more frequent, wider coverage), ALOS-4 observe wider swath while keeping as higher spatial resolution as that of ...

Development of a retrodirective PARC for ALOS/PALSAR calibration

IEEE International Geoscience and Remote Sensing Symposium, 2003
A novel PARC of Van Atta array design is developed for polarimetric calibration of PALSAR onboard the ALOS satellite. The PARC consists of four dual-polaraized 3/spl times/3-cross-dipole subarrays. The Van Atta array configuration combining with dual-polarized nature of the subarrays provides the PARC the depolarizing and retrodirective characteristics

Performance of ALOS-2 PALSAR-2 for disaster response

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
In 2016, the Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”) observed various disaster affected areas. Japan Aerospace Exploration Agency (JAXA) operated the emergency observation more than hundred times in the year. The Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard ALOS-2 contributed for detecting the disaster affected
