A mathematical transform, called the Rosette Transform, together with a new method, called the Dense Sampling Method, have been developed. The Rosette Transform is invented to apply to both the mean part and the fluctuating part of a targeted radar signature using the Dense Sampling Method to construct the data in a high-resolution grid at 1-km posting for wind measurements over water surfaces such as oceans or lakes.
This new technique enables the use of NASA satellite scatterometer data, such as QuikSCAT data, which have been collected globally over a decade for measuring high-resolution wind field at 1-km posting on water surfaces. Valid in nearshore waters (10–15 km from shore), the high-resolution wind data are unique and critical to calculate accurate wind power density and its variability for the development of future offshore wind farms. The new technique was originally developed to monitor urban and suburban environments, and it has been applied to obtain high-resolution radar signatures over ocean and lake environments for high-resolution wind measurements.
