Abstract :
Use is made of the Fourier integral to derive an expression for the radiation field of spherical reflectors which are corrected for spherical aberration with the use of a subreflector. Calculations for some cases of interest show the sidelobe radiation to be 5.6 dB higher than in a uniformly illuminated aperture.
