Applications of MBPE for RCS Fast Calculation of 3D PEC Objects
|
Abstract:
An implementation of the Model Based Parameter Estimation(MBPE) technique 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.
