| dc.description.abstract | A method for raw signal generation for extended SAR (Synthetic Aperture Radar) scenes with very high resolution is
described. Such a simulator shall handle resolution better than 30 cm, squinted geometry, elliptical orbit motion and use
a polarimetric reflectivity matrix. Classical polarimetric scattering theory is based on electromagnetic harmonic fields
using Maxwell’s equations, Green’s function, Huygens’ principle and Kirchhoff’s approximation. Here, the scattering
theory is modified for a chirp field. Calculated expressions for the scattered chirp field or the reflectivity matrix in the
single scattering case are presented. Such a reflectivity matrix can then be input to the Inverse-EETF4 (Extended Exact
Transfer Function 4th order) for raw data generation. | en_GB |
