Description:
Study results are presented showing performance capability of a spaceborne scatterometer to operationally measure ocean surface wind speed and direction. In addition, a research mode is described which will allow development of improved radar signatures for ocean, sea ice, and land targets. The study results show that a scatterometer can meet the operational requirements of + or - 2 m/s wind speed accuracy (or + or - 10%, whichever is greater) and + or - 20 deg wind direction accuracy over most of the expected ocean surface conditions. The six beam scatterometer design evaluated is shown to be skillful (greater than 90% correct) in specifying the correct wind vector solution (with a 180 deg ambiguity) from the multiple solutions derived; further improvement must rely on meteorological and pattern recognition techniques now under study.
