Well, it ain't quite a Nobel Prize, but I just learned that US Patent #7,280,897 was awarded this month - with my name on it.
As I've been retired since 2001 you can see how slowly the wheels turn in the Patent Department of Lockheed Martin and the US Patent Office.
You can see it at: http://www.freepatentsonline.com/7280897.html.
It has to do with determining "intervisibility" between two points in a 3D space using a digital terrain map.
Although the method has many possible practical uses, the context for our work was to protect a helicopter flying at low altitude from threats. Given the locations, heights, and effective ranges of multiple threats, and a digital terrain map, the algorithm and method rapidly calculates the 3D cells that can and cannot be seen by those threats.
(A related algorithm and method, patented in 2001 and also with my name on it, calculates the 3D path a helicopter should fly between points "A" and "B" to minimize chances of being seen by threats while avoiding running into the terrain. See http://www.freepatentsonline.com/6259988.html)
