ASAR-Envisat's Advanced Synthetic Aperture Radar

摘要

Following on from the highly successful ERS-1/2 SARs, whih have contributed to major scientific achievements and initiated pre- operational and commercial applications of SAR data, ESA is now ready to launch Europe's largest remote-sensing satellite to data, carrying an Advanced Synthetic Aperture Radar (ASAR). The ASAR is an all-weather, day-and-night high-resolution radar- Imaging instrument. Compared with the ERS SAR, it features extended Observational capabilities, three new modes of operation and Improved performances.
