Abstract :
An exact method for imaging perfectly conducting bodies by means of high-frequency scattered field data is determined. A surface wave traveling on a three-dimensional curved body is treated. The explicit contributions of various diffraction phenomena to surface current are used to obtain the method. The method for exactly determining the configurations of convex bodies is given by results which explain the contribution of surface currents to the scattered field. The uniqueness condition for the solution of the inverse problem is obtained.<>
