摘要：
An iterative inversion in angular spectral domain based on the quasi Newton's procedure is presented. Angular spectral-domain reconstruction is shown to be more insensitive to the noise in the scattered field than configuration domain reconstruction. It is also shown by closed-form solution of a homogeneous circular cylinder that the local minima hindering this inversion process exist in the cost function. (C) 1994 John Wiley & Sons, Inc.
