将均匀各向异性介质重构为电学上的无耗各向同性介质，得到了重构目标的散射截面；进而得到了主坐标系中无耗各向异性介质球的散射截面，将介质退化到各向同性介质时，各向异性介质球的散射截面与Mie理论完全一致，验证了所得结果的正确性；仿真结果表明：散射截面正比于目标介电常数张量的元素且随入射方向的变化而变化；所得结果为复杂形体各向异性介质目标的散射评判提供了理论基础。

The uniformly anisotropic medium is reconstructed as a lossless isotropic one in electricity, and its scattering cross section is developed. In primary coordinate system, the scattering cross section of a lossless anisotropic dielectric sphere is obtained. It is found that when the anisotropic medium is an isotropic one, the scattering cross section of this sphere is in agreement with the famous Mie theory, so the validity of the gaining result is tested. Simulations show that the scattering cross section is proportional to the element of the dielectric constant tensor and varies with the incident wave direction. For the scattering of a complex anisotropic medium target, this result provides an evaluation criterion.
