Chapter 1
The ASAR User Guide
The Advanced Synthetic Aperture Radar (ASAR) instrument
on board the ENVISAT satellite extends the
mission of the Active Microwave
Instrument (AMI) Synthetic Aperture Radar
(SAR) instruments flown on the European Remote Sensing
(ERS) Satellites ERS-1 and ERS-2. ASAR uses an
active phased-array antenna, with incidence angles between 15 and 45
degrees. Applications for this sensor will include the
study of ocean waves, sea ice extent and
motion, and land surface studies such as
deforestation and desertification, to name a few.
This User Guide will provide the reader with information
on the special features of ASAR data, as
well as how to select the type of
products best suited for specific
requirements. It also discusses how to use the data,
and provides a list of sources for further reading.
