An improved simulation model for spaceborne scatterometer measurements
Development of scatterometer designs and applications requires extensive data simulation. The advancing capabilities of instruments motivates our proposal for an improved simulation model for noisy scatterometer measurements. Previous simulation models do not separately account for the two forms of random variation—signal fading and additive noise—which affect scatterometer measurements. The pr...
متن کاملSpaceborne Scatterometer and Scientific Applications
Just a few decades ago, almost all ocean wind measurements came from merchant ships; the sparcity of which over the global ocean is well known. Today, many citizens believe that operational numerical weather prediction (NWP) will give us all the wind information we need, until a hurricane suddenly intensifies and changes course, or the delay of monsoon brings drought, or the Pacific Trade Wind ...

متن کاملCalibration of and Attitude Error Estimation for a Spaceborne Scatterometer Using Measurements over Land
The NASA Scatterometer (NSCAT) was launched August 20, 1996 aboard the National Space Development Agency of Japan's Advanced Earth Observing Spacecraft (ADEOS). NSCAT's primary mission was to measure radar backscatter over the world's oceans. These measurements are used to generate estimates of ocean wind speed and direction. Scatterometers must be calibrated before their measurements are scien...
متن کاملImproved resolution backscatter measurements with the SeaWinds pencil-beam scatterometer
The SeaWinds scatterometer was launched on the NASA QuikSCAT spacecraft in June 1999 and is planned for the Japanese ADEOS-II mission in 2000. In addition to generating a global Ku-band backscatter data set useful for a variety of climate studies, these flights will provide ocean-surface wind estimates for use in operational weather forecasting. SeaWinds employs a compact “pencil-beam” design r...
