摘要：
A method for raw signal simulation for extended SAR scenes with very high resolution is described. This simulator shall handle resolution better than I in, 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 are presented. Such a reflectivity matrix can then be input to the inverse-EETF4 for raw data generation.
