Deriving Ocean Surface Drift Using Multiple SAR Sensors

Remote Sensing, 2009
Tracking and monitoring ocean features which have short coherent time periods from sequential satellite images requires that the images have both very high spatial resolutions and short temporal sampling intervals (i.e., repeated cycles).
