| 摘 要： | 利用LOVE场等效原理．实现了从近场到远场的变换，很好地解决了应用时域有限差分法（FDTD）计算目标远场RCS（远场雷达散射截面）的问题，并应用Marlab编程成功实现了此算法．最后利用该方法求解了三个实例中的远场RCS问题．并将其计算结果与理论或其他计算方法所得的结果进行了比较．结果吻合较好．

| Abstract: | LOVE's Equivalence Theorem is presented to make the transform from near-field to far-field come true,and the far-field RCS problems are solved well in finite-difference time-domain method(FDTD).At the same time,the FDTDalgorithm is also achieved by use of Matlab program.Three examples about far-field RCS problems are worked out at last.The data calculated is compared with one in other method and the results show us that the method is feasible. |
