This work proposes an efficient and accurate approach for the high frequency analysis of the radiation from large irregularly contoured planar tapered phased arrays installed on complex platforms. The arrays are seen as the superimposition of parallel linear arrays. The radiation from each constitutive linear array is collectively described in terms of rays, associated to conical Floquet Waves, and spherical diffracted waves arising from the tips. The interaction of these relatively few rays with the complex environment can then be easily modelled by means of the geometrical theory of diffraction or the physical optics. Numerical results are shown in order to demonstrate the effectiveness of the proposed approach.
