The main concern of this study is the effect of incident wave properties on the resonance that occurs when the target size is close to the wavelength. In doing that, the laser radar cross-section of a conducting target is calculated using a boundary value method with a beam wave incidence and H-wave polarization. Therefore, the effect of creeping waves, produced with H-wave incidence, on the backscattering enhancement would be clarified. A comparison with a similar scattering problem using a plane wave incidence is considered.
