A collision sense and avoidance system and method and an aircraft, such as an Unmanned Air Vehicle (UAV) and/or Remotely Piloted Vehicle (RPV), including the collision sense and avoidance system. The collision sense and avoidance system includes an image interrogator identifies potential collision threats to the aircraft and provides maneuvers to avoid any identified threat. Motion sensors (e.g., imaging and/or infrared sensors) provide image frames of the surroundings to a clutter suppression and target detection unit that detects local targets moving in the frames. A Line Of Sight (LOS), multi-target tracking unit, tracks detected local targets and maintains a track history in LOS coordinates for each detected local target. A threat assessment unit determines whether any tracked local target poses a collision threat. An avoidance maneuver unit provides flight control and guidance with a maneuver to avoid any identified said collision threat.

What is claimed is: 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; andan 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.
