一个高频逆散射问题的稳定性估计

Stability estimates for an inverse scattering problem at high frequencies

Habib Ammari, Hajer Bahouri, David Dos Santos Ferreira, Isabelle Gallagher

摘要:

我们考虑了一个逆散射问题及其在高频下的近场近似。我们首先证明,对于这两个问题,Lipschitz稳定性结果确定的潜在的低频分量。然后,我们表明,在径向潜力的情况下,支持足够接近边界,无限的分辨率可以实现从测量的近场算子在单调的情况下。

英文摘要:

We consider an inverse scattering problem and its near-field approximation at high frequencies. We first prove, for both problems, Lipschitz stability results for determining the low-frequency component of the potential. Then we show that, in the case of a radial potential supported sufficiently near the boundary, infinite resolution can be achieved from measurements of the near-field operator in the monotone case.
