description.abstract	This paper deals with the scattering of a TE plane wave by a apodised sinusoidal surface. The analysis starts with the extended Floquet solution, which is a 'Fourier series' with 'Fourier coefficients' given by band-limited Fourier integrals of amplitude functions. The integral equation for the amplitude functions is derived and solved by the small perturbation method to get a single and double scattering amplitudes. Then, it is found that the beam shape generated by the single scattering is proportional to the Fourier spectrum of the apodisation function, but that generated by the double scattering is proportional to the spectrum of the squared apodisation. As a result, the single scattering beam 　and the double scattering beam may have different patterns of angular distributions. It is demonstrated that the sidelobes are much reduced 　if Hanning window or Hamming window is used as an apodisation function.
