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