Radarsat-2 satellite
The canadian Radarsat-2 C-band radar satellite was launched on December 14, 2007 by a Russian Soyuz-FG rocket from the Baikonur cosmodrome. Radarsat-2 represents a new generation of commercial radar satellites and was created as a result of an agreement between the government — the Canadian Space Agency, the manufacturer — MacDonald, Dettwiler and Associates Ltd. (MDA), which is the operator of the satellite and ground segment.

The Radarsat-2 spacecraft has significant technical advantages over the Radarsat-1 spacecraft, including three-meter resolution, flexibility in the choice of polarization, the ability to take left and right side shots, and more accurate measurement of the satellite's position in orbit.
Technical characteristics of the Radarsat-2 spacecraft
SAR equipment provides the following polarization options:
- selective (HH и HV) or (VH и VV);
- single (HH);
- the quadruple (HH, VV, HV, VH);
- selective unit (HH) or (HV) or (VH) or (VV)
Technical characteristics of SAR equipment
Main directions of using data obtained by Radarsat-2 spacecraft:
