| Abstract: | This paper invesgigates the ocean surface wind field detection of a Ku band space-borne
scan-scatterometer. The resolution cell extraction method and the wind vector ambiguous solution are
presented. The ground and space flight calibrating and scatterometer working characteristics are analyzed.
The simulation has shown the effectiveness of wind field detection of this scatterometer and the backscat-
ter model (Moore equation) ur}er homogeneous and whirl wind fields respectively. |
