We present a method of estimating the shape of a weakly scattering binary convex polygonal object from the backscattered field. We use the concept scattering centers where it has been possible to model the scattered field as a sum of complex sinusoids. All corners of an object could be estimated with three or more illuminations, but of which at least two are in orthogonal directions. Using the amplitude of the sinusoids, we have also resolved the ambiguity in joining the corners when there are more than one object
