| Abstract: | A new method of computing RCS of complicated targets based on the graphical electromagnetic computing is presented, and the combining method of targets modeling with targets brink identification is applied, so the edges of target are able to be identified accurately and precision of the results is improved. The error of the physical optics field of edge which is computed twice is corrected by using physical theory of diffraction, The combining method of PTD and ECM is used in the disquisition. |
