Spaceborne Compact Polarimetric Synthetic Aperture Radar for Ship Detection

Leida xuebao, 2016
Spaceborne Compact Polarimetric Synthetic Aperture Radar (CP SAR) is a new form of SAR, which has intrinsic advantages in maritime surveillance because it can obtain relatively rich polarimetric information of targets with wide swath.
