Abstract:
Graphical Electromagnetics Compution(GRECO) is very efficient for scattering simulation of complex object,and it is applied to obtaining the broadband radar echo of fast-moving object for different broadband signals.In order to verify the simulation results,2-D ISAR(Inverse Synthetic Aperture Radar) images are obtained by using motion compensation method for fastmoving object and conventional motion compensation method.The high efficiency of GRECO ensures that the method can be applied in the field of radar engineering.
