Abstract :
Along track interferometric (ATI) synthetic aperture radar (SAR) has the capability of detecting moving targets and measuring the line-of-sight velocity of the target. With the ATI SAR, the current velocity map can be obtained by combining two perpendicular ATI data sets recorded over sea in rapid succession. In this paper, we describe how sea surface current can be mapped using airborne Ku-band SAR and present results of sea surface current at Cape Irago in Japan.
