Abstract
An iterative inversion in angular spectral domain based on the quasi N ewton's procedure is presented. Angular spectral-domain reconstruction is shown to be more insensitive to the noise in the scattered field t han configuration domain reconstruction. It is also shown by closed-fo rm solution of a homogeneous circular cylinder that the local minima h indering this inversion process exist in the cost function. (C) 1994 J ohn Wiley & Sons, Inc.
