ALOS-2 Satellite Capabilities
Advanced L-Band SAR Imaging for Environmental, Disaster, and Infrastructure Monitoring
About the ALOS-2 Satellite
ALOS-2 (Advanced Land Observing Satellite-2), operated by the Japan Aerospace Exploration Agency (JAXA), is an advanced Earth observation satellite designed to deliver high-resolution L-band Synthetic Aperture Radar (SAR) imagery. Since launch, ALOS-2 has supported a wide range of applications including environmental monitoring, disaster response, land deformation analysis, agriculture, and infrastructure assessment.
With its ability to capture data day or night and in all weather conditions, ALOS-2 provides reliable and consistent imaging for national mapping, hazard detection, and long-term environmental and geophysical monitoring. Its diverse imaging modes—including spotlight, ScanSAR, and polarimetric options—enable tailored data acquisition to meet the needs of government, commercial, and scientific users.
Comprehensive Monitoring
Provides large-area coverage ideal for land, coastal, and environmental monitoring, disaster response, and change detection.
Wide Swath Width
Offers wide-area SAR imaging for urban planning, agriculture, and regional environmental assessment.
Flexible Imaging Capabilities
High-resolution spotlight mode and left/right look capability support 3D modelling, terrain mapping, and precise deformation studies.
Key Features and Benefits of ALOS-2
- Equipped with an advanced L-band SAR system, enabling high-resolution imaging regardless of cloud cover, daylight, or weather conditions.
- Supports multiple observation modes including Fine, ScanSAR, and Polarimetry, allowing users to customise acquisitions for specific applications such as agriculture, forestry, and geology.
- Wide-swath imaging enables regional and global-scale monitoring across land, coastal, and maritime regions.
- Provides highly accurate and repeatable measurements for detecting subtle land surface changes, geological movement, and long-term environmental trends.
- Short revisit intervals allow timely monitoring of rapidly changing environments, emergency situations, and operational planning.
- Fully compatible with InSAR (Interferometric SAR) analysis for land deformation, subsidence, seismic studies, and infrastructure stability assessments.
