Abstract :
Radon transform(RT) interpretation of the physical optics integral and application to near and far field acoustic scattering problems are reported. Closed-form expression of the radiation integral will be found for both acoustically soft and hard surfaces, and it will be shown that as a consequence of the RT interpretation of PO integral, the surface integral reduces to a line integral over the intersection curve. The line integral will be evaluated and analytical formulae for the scattered field will be developed for the triangular patches.
