Microwave imaging in angular spectral domain based on the improved Newton's procedure

Abstract

Abstract 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. © 1994 John Wiley & Sons, Inc.
