The Effect of Coma Aberration on Point Spread Function for Array Synthetic Circular Obscured Aperture

Adnan Aldehadhawe, Ban Hussein Ali Alrueshdy

Abstract


In this research we study the effect of coma aberration on point spread function (PSF) for array synthetic circular obscured aperture. The equation of point spread function (PSF) have been derived for this case, coma aberration is used in different angles for set of obscured circular synthetic apertures, addition to different obscuration ratios, by using MathCAD programs. The results show an increasing the resolving power by using array synthetic circular obscured aperture and coma aberration leads to decrease the secondary peaks for point spread function (Apodization).
