Theoretical models for bistatic scattering based on the Kirchhoff approximation could be insufficient in some situations. An alternative, small-slope approximation of the lowest order is considered for calculations of normalized bistatic cross-section of an ocean surface for L-band radio waves. Numerical results are obtained for two spectral models of the ocean surface as a function of wind speed, wind direction, scattering angles and polarization states
