摘要：

The problem of determining the surface impedance of an obstacle from measurements of the far field pattern of a scattered time harmonic acoustic wave is considered. It is shown that this problem can be stabilized by assuming that the impedance is Holder continuous with an a priori bound given on the impedance and its Holder coefficient. A constructive method for determining the impedance is given through the use of the Backus-Gilbert method for solving improperly posed moment problems.
