ABSTRACT:
A system for automatically acquiring a target with a narrow field-of-view gimbaled imaging sensor. The system includes a target-detection subsystem including one or more target-detection imaging sensor with a first field-of-view, a target-tracking subsystem and a processing system in communication with the target-detection subsystem and the target-tracking imaging subsystem. The target-tracking subsystem includes a target-tracking imaging sensor with a second field-of-view smaller than the first field-of-view, and a gimbal mechanism for controlling a viewing direction of the target-tracking imaging sensor. The processing system includes a target transfer module responsive to detection of a target by the target-detection subsystem to process data from the target-detection subsystem to determine a target direction vector, operate the gimbal mechanism so as to align the viewing direction of the target-tracking imaging sensor with the target direction vector, derive an image from the target-tracking imaging sensor, correlate the image with one or more part of an image from the target-detection subsystem to derive a misalignment error, and supply the misalignment error to the target-tracking subsystem for use in acquisition of the target.
