TELEPHOTO SYSTEMS FOR SIDEWINDER-TYPE SEEKERS (A PRELIMINARY STUDY)
Abstract
A telephoto Sidewinder seeker, similar to the standard optical systems in the Sidewinder family except that a negative mirror is substituted for the normally flat secondary mirror, is compared with a standard system of the same aperture. Calculations (made for a particular case with the focal length of the telephoto about twice that of its standard counterpart) show that because of the residual aberrations, the angular image size for the telephoto is somewhat greater and thus the resolution is poorer than that of the standard system.
