Abstract :
Two computer codep have been developed at DLR in order to calculate bistatic RCSs. The first code treats the high frequency case and is based on the physical optics (PO) method. The second one is suited for objects with dimensions comparable to the wavelength and is based on the finite-difference time-domain (FDTD) method. For test objects with perfectly conducting surfaces (a sphere and an elliptical cylinder) numerical results of the codes are compared and validated with those of the IEM-code NEC-2, analytical solutions and experimental results achieved by measurements at 94 GHz.
