China's first synthetic-aperture
radar (SAR) satellite for environmental monitoring has produced
its first "clear, coherent and informative" image of Earth,

The image was then sent to a station located at the Academy of

Beijing, the statement said.
"Compared with optical imaging satellites, the SAR
environmental monitoring satellite has greatly enhanced the
efficiency and overall ability of the country's Earth observation

monitoring satellite, according to north China's Taiyuan Satellite
Launch Center, where the satellite was launched.
The radar satellite joined two optical satellites launched in
September 2008, forming a network that covers most of China's
This satellites will help provide scientific evidence for
assessing natural disasters, emergency aid and reconstruction, as
well as enable China to monitor and forecast ecological changes,
pollution and natural disasters around the clock, the center said.
