In this article a technique is proposed to reduce the contribution from support structures during backscattered field measurements of objects. The contribution from support structures contaminates the backscattered field from objects with low radar cross‐section (RCS) or stealth characteristics. The technique employs microwave imaging algorithms to obtain an image of the object. The unwanted contribution from the support structure to the total backscattered field is removed. Using a reconstruction technique, the RCS of the object is obtained from the clean image. The proposed technique is applied to obtain the RCS for an object measured in the compact range at the University of Pretoria, South Africa. © 1996 John Wiley & Sons, Inc.
