The high frequency asymptotic approach to diffraction by strongly elongated bodies is generalized to the case of the impedance boundary conditions. However, this is done only in the limiting case of infinitely flat elliptic cylinder. The representations for the field in the boundary-layer near the surface of the strip and for the radar cross-section in the case of small scattering angles are derived and tested.
