Abstract: A formulation of radar cross section (RCS) for smooth convex metal objects coated with radar absorbing material (RAM) is derived. RCS has been measured and calculated for a series of metal planes coated with RAM. To improve accuracy of calculation, an engineering correction is given. Finally, the wing is coated with RAM at its leading edge and trailing edge. The result of study shows that RCS is efficiently controlled by coating RAM at the leading edge and the trailing edge of the metal wing.
