Application of spaceborne SAR imagery in monitoring green algae

Synthetic Aperture Radar (SAR) satellite image is first used to monitor dramatically growing green algae near Qingdao coastal in 2008. The system played important role in ensuring Qingdao 2008 Olympic Sailing Competition. Based on imagery statistic analysis, the influences of radar parameter on detection performance are evaluated. A processing method which used in practice is presented. Processing results consist with field observation data well, which validate the feasibility of the method.
