Airborne polarimetric SAR monitoring for ships and coastal seas

Airborne polarimetric and interferometric synthetic aperture radar (PiSAR) images are analyzed for monitoring ships and coastal seas especially for estimating sea surface wind speed and direction. Though
in situ
ships data through AIS (Automatic Identification System) were not available by the time of analysis, PiSAR's X band images showed the potential to map coastal wind vectors with high spatial resolution of 2.5 m
