RADARSAT Data

RADARSAT-2, the next-generation commercial SAR satellite, was launched in December, 2007.

RADARSAT-2 has been designed with significant and powerful technical advancements which include 3m high-resolution imaging, flexibility in selection of polarization, left and right-looking imaging options, superior data storage and more precise measurements of spacecraft position.

Example imagery captured in 2008 is available to view here.

SAR Imagery

SAR imagery has proved its usefulness to applications both onshore and offshore for a number of years now. Its capability to penetrate cloud, rain, dust and haze allows data to be collected both day and night. This is particularly useful where persistent cloud cover or poor illumination hamper the collection of optical data. In contrast to optical imagery, SAR is an active sensor. The return signal strength depends primarily on:
