Multiframe blind deconvolution - the process of restoring resolution to blurred
imagery when the precise form of the blurs is unknown - is discussed as an
estimation-theoretic method for improving the resolving power of ground-based
telescopes used for space surveillance. The imaging problem is posed in an
estimation-theoretic framework whereby the object’s incoherent
scattering function is estimated through the simultaneous identification and
correction of the distorting effects of atmospheric turbulence. An iterative
method derived via the expectation-maximization (EM) procedure is reviewed, and
results obtained from telescope imagery of the Hubble Space Telescope are
