 This was developedfor radar measurements, but is comparable to other signature development areas for other sensors and may be used for hyperspectral sensing of buried objects.In applications of intelligence interest, the Johns Hopkins University Applied Physics Laboratory (JHU/APL) has demonstrated that hyperspectral sensing allows discrimination of refined signatures, based on a large number of narrow frequency bands across a wide spectrum.These techniques can identify include military vehicle paints, characteristic of particular countries' signatures.
