| 摘 要： | 为了突出雷达波自身的动力学特点，本文首先用Ｇａｌｅｒｋｉｎ’ｓ方法推导了含衰减项的雷达波有限元方程，用有限元方法实现了管状体、弯曲界面等复杂形体的雷达波场的仿真模拟．通过对比同一模型合衰减和不含衰减两种情况的波场，明显地展示了考虑雷达波自身特点后的波场仿真性较好．

| Abstract: | In order to highlight the dynamic characteristics of radar wave, we derive thefinite element equations of radar wave with attenuated term using Galerkin's methed,and complete the radar wave field simulation with finite element method for complexbodies, such as pipe model, curve interface model et al. The model examples showthat radar wave profile in which the attenuated term is considered is much better thanthat the attenuated term is neglected. |

| Keywords: | Radar wave attenuation Finite element modeling. |
