摘要
文中利用图形电磁计算方法计算了复杂目标远场的雷达散射截面,运用了目标建模与目标边缘识别相结合的方法,完成了对目标边缘的精确识别,增加了计算的精度;同时,修正了几何绕射场存在物理光学重复计算的问题,引入了物理绕射系数和等效电磁流相结合的方法。
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.
