| Abstract： |
The authors prove the uniqueness in the inverse acoustic scattering problem within
convex polygonal domains by a single incident direction in the sound-soft case and the
sound-hard case, and by two incident directions in the case of the impedance boundary
condition. The proof is based on analytic continuation on a straight line. |
