| 摘 要： | 针对时域积分方程中存在的晚时震荡问题，介绍了基于Laguerre多项式的电场、磁场和混合场积分方程，求解了导体球和导体圆柱的时域电流分布和后向散射场以及单站RCS。结果表明，3种积分方程很好地解决了晚时震荡问题，混合场积分方程具有更高的计算精度。

| Abstract: | In order to eliminate the late-time-oscillate in time domain integral equation, EFIE, MFIE and CFIE which based on the method of MOD using Laguerre polynomials as temporal basis function were introduced, induced current distributing and backward scattering of far field in time domain and monostatic RCS of a conducting sphere and a cylinder were given. The results showed that they eliminate the late-time-oscillate effectively and the CFIE has higher precision than the other two. |
