Wavelength dependent radiometric modeling for an active Geo-Synchronous satellite imaging system

摘要

Recent interest in imaging satellites in geo-synchronous earth orbit has led to the design of a ground-based active imaging system using a concept known as Fourier Telescopy. Fourier systems use active laser illumination. aperature synthesis, and extensive computer processing to minimize atmospheric turbulence effects and form high-resolution images of distant stationary objects. Three laser transmitters of slightly different frequency illuminate the object with varying baseline separations to temporally encode object spatial frequency information in the energy backscattered from the object.
