WSS Mosaic

ASAR WSS Mosaicking


ASAR WSS products differ from conventional image products in that the data from the five subswaths acquired by five antenna beams SS1 through SS5 are stored in separate image records. The five WSS beams acquire data with a substantial overlap (typically several hundred range samples, ~ 9 Km). The incidence angle variation of 16 to 43 degrees across beams SS1 through SS5 creates large differences in the nominal near and far range backscatter intensities. An ASAR WSS product is delivered as a single data file containing the subswath data records arranged sequentially.

Use can use the Graph for Deburst, Calibrate, Detect and Mosaic an ASAR WSS product. It will deburst and split the WSS product into five subswath products, apply calibration and multilook and then mosaic them back into one product.
