摘要：

Radarsat is a Canadian-led cooperative program with the United States to launch and operate a remote sensing satellite with a Synthetic Aperture Radar (SAR) sensor. The spacecraft is scheduled for launch into a sun-synchronous dawn-dusk polar orbit in 1994 on an expendable Delta II launch vehicle for a five-year mission. The mean orbit altitude and inclination are 789 km and 98.6°, respectively. The right-looking SAR, with the unique ability to shape and steer the radar beam over an 500-km accessibility swath, will provide daily Arctic coverage, coverage of the Canadian land mass every 3 days, and coverage of the globe every 24 days. A wide variety of swath widths, incidence angles, and resolutions can be selected. The SAR can also be oriented to the left of the flight path to enable coverage of central Antarctica. The objective of the Radarsat program is to gather data of both applicatons and research value related to global ice, oceans, and renewable and nonrenewable resources. The spacecraft will have an ability to store the instrument data that can later be transmitted to an appropriate data-acquisition station, thus ensuring global coverage. © 1990 IEEE
