Inertially-assisted target detection

A target detection system includes an imager that sequentially captures frames, in different emission bands. These frames are registered with respect to one another based on information from an Inertial Navigation System (INS) and compensation is made for any motion of the imager between frames. Ide...

Zusammenfassung:	A target detection system includes an imager that sequentially captures frames, in different emission bands. These frames are registered with respect to one another based on information from an Inertial Navigation System (INS) and compensation is made for any motion of the imager between frames. Identification of a candidate target object that is detected, or otherwise identified in one band, initiates a search for a correlated object in the other band within a radius, or distance, in a common image-space reference frame. When a pair of objects is identified, a measure of the intensities of the signals in the two bands is compared to an expected range of values to discriminate a target of interest from an object that is not of interest.
