(abstract) Two-Dimensional Surface Current in the Coastal Environment Using Vector Along-Track Interferometry

The structure of surface currents in the coastal environment can be very complex as it is governed by a multitude of factors such as local bathymetry, sea state, etc. Knowledge of the structure of coastal currents is a key requirement in the ability to carry out safe maneuvers and landings in an unknown coastal situation. Furthermore, it is desirable to have the ability to obtain such information by remote sensing and in a timely manner. We present a remote sensing technique which has the potential to meet certain specific requisites. We will present a theoretical discussion of the measurement technique, then will demonstrate the technique using data previously acquired and compare the results against conventional along-track interferometric measurements.
