利用因式分解方法研究了未知散射体由两个不同物理性质的目标组成时的逆声散射问题。特别是，我们考虑了以下两种情况：一种是每个物体的边界条件不同的情况，另一种是渗透率不同的情况。我们的想法是根据情况修改远场算子，以避免不必要的先验假设。
We study an inverse acoustic scattering problem by the factorization method when the unknown scatterer consists of two objects with different physical properties. Especially, we consider the following two cases: One is the case when each object has the different boundary condition, and the other one is when different penetrability. Our idea here is to modify the far‐field operator depending on the cases to avoid unnecessary a priori assumptions.
