RADARSAT-1 & RADARSAT-2 Satellite Capabilities

C-Band SAR Imaging for Environmental Monitoring, Maritime Surveillance, and Resource Management

About RADARSAT-1 & RADARSAT-2

RADARSAT-1 (launched in 1995) and RADARSAT-2 (launched in 2007) are Canadian C-band Synthetic Aperture Radar (SAR) Earth observation satellites designed to deliver high-quality radar imagery for global monitoring applications. Operated as national assets supporting government, scientific, and commercial needs, both satellites offer robust, weather-independent data acquisition, capturing imagery day or night, through cloud, smoke, and atmospheric interference.

With flexible beam modes and multiple imaging configurations, RADARSAT-1 and RADARSAT-2 support diverse uses including environmental monitoring, maritime domain awareness, agriculture, natural resource management, ice monitoring, and geohazard assessment. Their reliable SAR capabilities make them essential tools for long-term monitoring of coastal zones, infrastructure, land deformation, and disaster-affected regions.

High-Quality Radar Imaging

Delivers detailed C-band SAR imagery that reveals land features and surface texture often not visible in optical data.

Mapping Structural Features

Ideal for identifying faults, folds, lineaments, and landform changes—supporting geohazard monitoring and resource exploration.

All-Weather Day/Night Imaging

SAR imaging provides uninterrupted data collection regardless of weather or lighting conditions, critical for disaster response.

Key Features and Benefits

• C-band SAR imaging allows RADARSAT-1 and RADARSAT-2 to acquire consistent imagery for environmental monitoring, maritime surveillance, and land management.
• SAR technology reveals that optical sensors may miss, supporting infrastructure monitoring and geophysical studies.
• Well-suited for mapping structural land features such as faults, folds, and lineaments, making the satellites essential for geohazard assessment.
• Capable of collecting data in both ascending and descending passes, enabling reliable monitoring of floods, oil spills, earthquakes, and other natural disasters.
• All-weather, day/night imaging ensures continuous data availability during storms, cloud cover, and nighttime operations.
