Abstract :
In this paper a simple method for relative antenna calibration is applied to NSCAT (NASA Scatterometer), and the model used is described. Calibration data sets are extracted using high-resolution masks. Results are presented for the Amazon rain forest (traditionally used) and the Siberian plain. Beam correction tables are derived for balancing normalized radar backscatter coefficient measurements from different antennas
