摘　　要：基于电磁场的多尺度变换理论,重整各向异性介质椭球电磁参数和形体参数,研究了各向异性介质椭球的电场分布,对所得结果进行了检验,得到了各向异性椭球目标的散射截面。结果表明:入射电场的方向,介电常数张量对各向异性椭球散射有较大的影响,形状参数影响不大,所得结果对复杂的各向异性目标散射研究有一定的指导意义。The distribution of electric field of an anisotropic medium elliptical sphere is presented by reforming both the electromagnetic parameter and shape parameter of this elliptical sphere based on the scales transformation of electromagnetic theory.The obtained results are tested.The RCS of the anisotropic target is founded.Simulations show that the direction of incident electric field and the dielectric constant tensor influences RCS remarkably but the target＇ size has not a great effect on it.The obtained results have some significance in the research of electromagnetic scattering by a complicated anisotropic target.
