  In a companion article, we discussed the radiometric sensitivity and
resolution of a new passive optical sensing technique, Space-Time Projection
Optical Tomography (SPOT), to detect and track sub-cm and larger space debris
for Space Situational Awareness. SPOT is based on the principle that long
synthetic exposure can be achieved if the phase-space trajectory of a
hypothetical point-source is precisely predictable within a very wide telescope
field-of-view, which is the case for orbiting debris. This article discusses
the computational search space for debris mining as well as a recursive
measure-and-fit algorithm based on a generalized Hough transform for orbit
determination.
