Digital Processing of Synthetic Aperture Optical Imagery.

Abstract

The synthetic aperture approach offers an attractive method for obtaining high resolution imagery with low mass, space-borne optical telescopes. This report presents a simple but effective method which allows the processing of dilute-array synthetic aperture optical data in such a way that aberration effects, introduced by unspecified improper positioning of telescope mirror segments can be removed. It is especially well-suited to two-mirror-segment synthetic aperture telescopes, which are characterized by low mass and comparatively good signal-to-noise ratio characteristics. Although there are restrictions on the spectral bandwidth allowed in the imaging process, the method can nonetheless be applied to multispectral imagery. Adoption of the method to the imaging of astronomical subjects through the turbulent atmosphere is also discussed.
