Abstract:
A system for identifying a position of an airborne platform on a flight path which comprises:a radar means mounted on the platform for directing an â€œnâ€  number of radar beams on respective predetermined paths toward the surface of the earth to generate an â€œnâ€  number of return signals, wherein â€œnâ€  is at least equal to three; an electronic means connected with said radar means for using said â€œnâ€  number of return signals to compute a ground speed, a direction of flight and an altitude for the platform to identify the position of the platform on its flight path; and a computer means preprogrammed with site-specific radar clutter model data for matching with said return signals to establish a start point location on the flight path to determine a route of flight for the platform.
