| 摘 要： | 采用直接FDTD方法对雷达波在等离子体包覆目标附近的总场和散射场分布进行了仿真。通过远-近场变换计算了远场电场和不同等离子体分布情况下的目标雷达散射截面RCS值。仿真结果表明,采用等离子包覆的方法可以有效地降低目标的RCS值。等离子体密度和厚度对目标RCS的影响较大,等离子体碰撞频率对目标RCS有一定的影响。

| Abstract: | The total field and the scattering field around plasma coated target were simulated with the direct FDTD method. The RCS value of metal targets coated by different plasma was calculated with the far-near field transform technique. Simulation results show that the plasma coating method can effectively reduce the RCS value of metal targets. Density and thickness of the coating plasma can greater impact on the RCS value, while the plasma collision frequency has a relatively less effect. |
