Abstract
Abstract A hyperspectral detection and seeking system for use in air-to-air, air-to-ground and ground-to-air missiles. The hyperspectral detection and seeking system includes a hyperspectral imaging system and a tracking system. Hyperspectral signatures for targets of interest may be either observed directly prior to launch or preloaded into the detection and seeking system. A tracking system provides for tracking of a target matching the preloaded or hyperspectral signature observed prior to launch. The hyperspectral detection and seeking system thus provides relatively higher precision for detecting and seeking targets with hyperspectral signatures. Since such hyperspectral signatures are formed from literally hundreds of spectra, the system is virtually immune to countermeasure since any countermeasures would effectively have to match its own hyperspectral signature over a relatively wide spectral range.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A target detections, seeking and guidance system for an air-to-air, air-to-ground and/or ground-to-air missile comprising a hyperspectral imaging system for detecting a target having a predetermined hyperspectral signature; means for enabling the missile to track the target matching the predetermined hyperspectral signature; and means including a missile controller for guiding the flight path of the missile to intercept the flight path of the target matching said predetermined hyperspectral signature.
Claim 2
Dependent Claim
69 words
A target detections, seeking and guidance system for an air-to-air, air-to-ground and/or ground-to-air missile comprising a hyperspectral imaging system for detecting a target having a predetermined hyperspectral signature; means for enabling the missile to track the target matching the predetermined hyperspectral signature; and means including a missile controller for guiding the flight path of the missile to intercept the flight path of the target matching said predetermined hyperspectral signature.
Claim 3
Dependent Claim
