基于电流密度拉普拉斯变换FDTD(CDLT-FDTD)方法,计算并验证了一维情况下的法拉第旋转效应、三维情况下磁化等离子体球的后向雷达散射截面(RCS),与其他方法计算结果一致。通过该方法计算并分析了任意磁化方向下磁等离子体涂敷准火箭模型的后向RCS的变化情况,计算结果表明磁化等离子体能有效减小目标的RCS。
Based on the current density Laplace transfer finite-difference time-domain(CDLT-FDTD) method,the Faraday rotation effect in 1-D and the radar scattering cross-section(RCS) of the magnetization plasma sphere in 3-D are computed respectively.And the results is in good agreement with the other methods.The method is applied to the electromagnetic scattering of similarity-rocket model coated with arbitrary magnetization direction plasma.The results show that the magnetized plasma may efficiently reduce the RCS of a metallic target.
