Abstract An implementation of the Model Based Parameter Estimation(MBPE) tech-nique is presented for obtaining the RCS frequency response of arbitrarily shaped Perfect Electric Conductor (PEC) bodies. The electric current is expanded in a Taylor series or Pade rational function around the frequency of interest, thus the -scattering field is obtained over the bandwidth. Rational function fitting model is also used for the interpolation of RCS in both spatial domain and frequency domain. A good agreement can be seen between MBPE and the exact solution, and the computational burden is significantly reduced.
