Abstract	A new, fast, two-dimensional method to find the shape of a dielectric and perfect electric conductor body from their scattered electric fields is presented. Initially, the shape distortions and the scattered field variations are related with a simple exponential relationship. Then, the error function between the field scattered by a first guess and the observed field scattered by the actual contour is minimized to find the distortions, and thus the actual shape of the object. Multiple frequencies are iteratively used to improve the reconstruction results. The behavior of the proposed algorithm is shown for both bistatic and monostatic radar configurations in various application examples.
