1. An image interrogator identifying and avoiding potential collision threats, said image interrogator comprising: a clutter suppression and target detection unit detecting moving targets from local images; a Line Of Sight (LOS), multi-target tracking unit tracking detected said targets from each target's focal plane track and from attitude; a threat assessment unit correlating a LOS track for said targets to construct a three-dimensional (3D) relative trajectory for each of said targets and determining from said 3D relative trajectories whether any tracked target poses a collision threat; and an avoidance maneuver unit determining a maneuver to avoid any identified said collision threat, wherein said image interrogator is vehicle mountable, and when mounted on an unmanned vehicle guiding said unmanned vehicle in unchaperoned travel in 3D space.
