Abstract:
In this research we derived the equation of optimum balance for spherical aberration from five order for array of obscured circular synthetic apertures, also to calculating the value of optimum balance for set from obscured circular synthetic apertures (N=1,2,6,8), the obscuration ratio (ε=0,0.25,0.5,0.75),by using Math LAB program, and derivative the equation of point spread function (PSF) for this case, by substituting the value of optimum balance in equation point spread function for spherical aberration from five order by using MathCAD program, the results show an increasing the values of spherical aberration coefficients from five order with increasing the apertures number, addition to increase the point spread function with increasing the obscuration ratio.
