RADARSAT-1, which stopped transmitting because of a technical anomaly in March 2013, was equipped with synthetic aperture radar (SAR), a powerful microwave instrument. It transmitted and received signals for capturing high quality images of the Earth night and day and in all-weather conditions. RADARSAT-1’s SAR transmitted a microwave energy pulse (C-band at 5.3 GHz frequency) to Earth, and the SAR measured the amount of energy reflected back to the satellite from the Earth’s surface.
The RADARSAT-1 SAR instrument was able to shape and steer its radar beam using C-band. A wide variety of beam widths were available to capture swaths of 45 to 500 kilometers, with a range of 8 to 100 meters in resolution and incidence angles of 10 to 60 degrees.
A restricted data access agreement is required to get Level 0, Level 1, or SLC data.
