我们提出了一种混合方法来数值求解形状和阻抗的反散射问题，给定一个入射方向的远场模式。该方法结合了迭代法和分解法的思想，继承了它们各自的优点，如得到良好的重构，并且每一步都不需要前向求解器。提出了一个优化问题作为该方法的理论背景，数值结果表明了该方法的可行性。
We present a hybrid method to numerically solve the inverse scattering problem for shape and impedance, given the far-field pattern for one incident direction. This method combines ideas of both iterative and decomposition methods, inheriting the advantages of each of them, such as getting good reconstructions and not needing a forward solver at each step. An optimization problem is presented as the theoretical background of the method and numerical results show its feasibility.
