Abstract :
The physical optics approximation is not applicable to the determination of electromagnetic scattering from obstacles that are not both large and smooth. In this paper, the second-order Born approximation has been utilized to determine the radar cross section of a fairly large, perfectly conducting finite cone. This method leads to radar cross-section values of proper magnitude for such cones, whereas the usual physical optics method yields cross-section values in error by an order of magnitude.
