{4}RADARSAT, is a sophisticated Earth Observation (EO) satellite developed by
Canada to support the monitoring of environmental changes and the management of
natural resources worldwide. Launched on November 4, 1995, it provides Canada
and the world with an operational and research users working in fields such as
agriculture, cartography, hydrology, forestry, oceanography, ice studies, and
coastal monitoring over the satellite's expected life span of five years.
Many optical satellites depend on sunlight illuminating the Earth in order to
obtain useful imagery. As such, their performance is restricted by the presence
of clouds, fog, smoke or darkness. However, RADASAT does not have those
limitations. At the heart of RADARSAT is an advanced radar sensor called Synthetic
Aperture Radar (SAR). RADARSAT'S SAR is a microwave instrument which sends pulsed
signals to see through clouds, haze, smoke and darkness, and obtain high quality
images of the Earth in all weather conditions and at any time. Also, RADARSAT
will generate for the first time a complete map of the Antarctica.
