Abstract: Wing is the important scattering source on the stealth. Scattering mechanism for its leading edge and trailing edge in the shadow region is analysed. A theoretical model of radar cross section of creeping waves on the leading edge and trailing edge for a two dimensional wing is presented. The effect of the shape of the wing on its radar cross section is considered in the model. It is very convenient for engineering estimation. Calculational results obtained by using this model are excellently in agreement with the results of one dimensional image for typical samples.
