An earlier method for the inverse diffraction problem, using only the backscattering cross section as a function of aspect angle, yields the profile curve for a strictly convex body of revolution. If the profile curve has straight line segments, the body is not strictly convex. Nevertheless, it is shown that the method, when applied to such a body, yields the correct profile except for a shortening of the straight segment by a factor which is at worst 0. 7.
