abstract

This paper discusses a novel approach to correct conformal missile dome aberrations with the addition of unique correction elements. For purposes of this study, an elliptical conformal dome with a fineness ratio of 1.0 and an index of refraction of 1.7 is used. A rotationally symmetric element, referred to as a 'fixed corrector', is capable o f some correction for roll-nod or azimuth- elevation gimbaling schemes. A non-rotationally symmetric corrector, referred to as an 'arch corrector' is capable of correcting roll-nod gimbaled missile seekers. Both methods are compared and the performance in terms of aberrations versus gimbal angle are reported.
