Abstract
This paper is described on optical aperture and electrical filter for the optical seeker. Two kinds of optical aperture are compared, that is, single and polarized double slits. In addition, the decision procedure of low-cut-off frequency of used electricity band-pass filter is shown. As a result, the double slit excels the about 1.25 to 2.33 times single slit on the SN ratio.
