Abstract :
Explicit expressions for the scattering of rotational symmetric high-frequency fields by a perfect conducting spherical sheet are obtained by surface currents induced on the cap. The results explain the contribution of surface currents to the scattered field and provide a method of obtaining the configurations of scatterers. The results can be used to describe an object by measurements at different points and check them with each other and analytical results.<>
