Uniqueness in Inverse Scattering Problems with Phaseless Far-Field Data at a Fixed Frequency. II
This paper is concerned with uniqueness in inverse acoustic scattering with phaseless far-field data at a fixed frequency. In our previous work [SIAM J. Appl. Math., 78 (2018), pp. 1737--1753], by utilizing spectral properties of the far-field operator we proved for the first time that the obstacle and the index …
