The exponential model is used to predict the high frequency values in the radar cross section (RCS) calculation. The Prony’s and Matrix-Pencil methods are presented to extract the parameters of exponential model. In particular, the Matrix-Pencil method is modified to increase the efficiency. Both methods are applied to a reference scatterer (a perfect electrically conducting sphere). Also, a new modelling scheme is proposed using the Legendre-basis functions. This approach is tested in the calculation of the bistatic RCS values.xviii, 106 leaves, illustrations , 30 cmEnglishinfo:eu-repo/semantics/openAccessMatrix-Pencil methodRCSextrapolationQA193 .G43 2002Matrix pencils.Radar cross section (RCS).Thesis
