The concept of utilizing radar-derived terrain-profile data for improving the guidance accuracy of weapon delivery systems has received considerable attention in recent years in the quest of ''zero'' CEP. One of the more successful concepts, to date, has been the Terrain Contour Matching (TERCOM) System being developed for cruise missile applications. Basically it obtains a position fix by correlating a radar-altimeter-derived terrain profile with stored topographical data. The location of the best match is taken to be the position of the vehicle. A sequence of such position fixes is used to update an inertial navigation system. (ERA citation 03:010850)
