A novel method of RCS fast calculation with complex antenna structure

A novel excitation source with more incident angle information is proposed based on compressive sensing (CS) theory, to overcome the traditional calculation difficulties. With the help of the Finite Element Software, a fast computational method of calculation mono-static radar cross section (RCS) is presented. The calculation results of monopole antenna, pyramidal horn antenna and parabolic antenna have verified the accuracy and computational efficiency of the new method.
