| Abstract: | In order to provide reliable templates for radar echo simulation and target recognition,2-D scattering data of the target are gotten with a hybrid approach of moment method and physical optics based on FEKO,after a CAD model is created.Those data are processed by 2-D fourier transform at forward angles to build the model of 2-D scattering centers.Theoretical analysis and simulation results show that the electromagnetic scattering properties are reflected correctly and effectively by this modeling method which has high practical applicable value for echo simulation and target recognition. |
