Abstract:

A computer program for calculation of the echo area of smoothly joined, N section convex conducting surfaces, described by a second degree equation is described. For the case of E theta parallel polarization of the incident and scattered fields the solution is obtained by a combination of geometrical optics and creeping wave theory. For the case of E phi perpendicular polarization the solution is obtained using geometrical optics, and the creeping wave is neglected. The computed results for E theta polarization are in good agreement with measurements for prolate spheroids, prolate spheroid-sphere, and prolate spheroid-oblate spheroid combinations.
