Image formation of orbital objects through the turbulent atmosphere using the Knox-Thompson algorithm is investigated. With the total observing time fixed by satellite dynamics, it is found that the percentage of the diffraction limit obtainable varies over most of its range as (r0/D)3/2. With ro roughly proportional to wavelength, longer observing wavelengths become attractive to maximize the obtainable resolution. Longer wavelengths are also preferred for daytime observations as the sky background decreases with increasing wavelength in the visible and near infrared. Observations at longer wavelengths suffer, however, from a decrease in the maximum obtainable resolution due to diffraction and the lack of efficient photoemissive materials beyond 0.9 ?m. The concept of a speckle imaging system spatial frequency cut off is developed and equations are derived to allow its calculation, including contributions from detector and sky background noise. The maximum system resolution as a function of wavelength is found to maximize, and equations are developed for the computation of the optimum observing wavelength.
