 By using state of the art technology, much
of the information can be shared, fused and used to improve the final
product. For example, scanning a wide area for time critical targets
cannot rely only on EO means alone. By merging GMTI and Stripmap SAR
images, wide areas can be scanned rapidly for moving targets, man-made
objects and potential targets. Such elements can be anything from a
pick-up truck to a transportable missile launcher. When potential
targets are detected, Spot mode is used to automatically scan through
each location in an attempt to distinguish differently shaped targets
such as a specific type of tank or truck. Known targets can be tagged
by their distinct signature, or actively marked for automatic
detection and tracking. SAR imagery is sufficient for identification
of military targets, identifying the distinctive 3D signatures and
object shapes of specific vehicle types; further investigation of the
target is required for engagement of typical targets in asymmetric
warfare.
 EO sensors are employed to further examine
specific locations or suspicious objects detected by the radar. By
fusing SAR, IIR, thermal and EO images, analysts can now focus on the
potential "needles", which automatic processes have weeded out of the
larger "haystack".
As all data is geo-referenced, target
coordinates can be extracted immediately for rapid response. The
fusion of signals from different spectral bands enable better
visualization of information which could be not be seen in by visible
means. The US Air Force pursues several Foliage Penetrating (FOPEN)
concepts, including processing of hyperspectral sensor data, for
collection, location, and identification of camouflaged and concealed
targets and foliage penetrating SAR.
