Abstract

Abstract:

The calculation method of monostatic radar cross section (RCS) is analyzed based on method of moment. When calculation of RCS is started by looping over angles, only the right voltage matrix is effected with the changes of the incidence wave. The left impedance matrix is not changed. Based on the characteristic, a new fast calculation method of monostatic RCS using Gauss elimination method is proposed. The elimination procedure is recorded when the monostatic RCS of the first angle is calculated, and the impedance matrix is transferred into product factors matrix. When the monostatic RCS of the other angles are calculated, only the right voltage matrix is calculated follow the elimination procedure of the first angle, thus the monostatic RCS calculating speed of the whole scale angels will be quickened greatly.

Key words: monostatic radar cross section, moment method, Gauss elimination method
